Time-Resolved Vibrational Spectroscopy covers the proceedings of the International Conference on Time-Resolved Vibrational Spectroscopy, convened in Lake Placid, New York on August 16-20, 1982. This book is organized into six sections encompassing 51 chapters. The first section deals with the theoretical and computational developments concerning Raman scattering and two-photon and optical spectroscopies. Section II focuses on the instrumentation and techniques of various time-resolved vibrational spectroscopies (TRVS), such as Raman techniques, stroboscopic interferometry, and infrared multiphoton. Sections III and IV deal with the chemical (ground and excited states) and biochemical systems of TRVS. The concluding sections discuss the theoretical principles and methods of observation of nonlinear Raman spectroscopy and surface-enhanced and colloidal Raman scattering. This book is of value to chemists, spectroscopists, and photobiologists.

The Sixth International Conference on Time-Resolved Vibrational Spectroscopy was held from May 23 to 28, 1993 in Berlin, Germany. It continued the series of biennial conferences initiated in 1982 by Prof. George Atkinson (University of Arizona) at Lake Placid, USA, followed by conferences which were chaired by Prof. Alfred Laubereau (University of Bayreuth) and Dr. Manfred Stockburger (Max-Planck-Institut, G6ttingen) at Bayreuth-Bischofsgrtin, Germany, in 1985, by Prof. Joop D.W. Van Voorst (University of Amsterdam) at Amersfoort, The Netherlands, in 1987, Prof. Thomas G. Spiro (Princeton University) at Princeton, USA, in 1989, and by Prof. Hiroaki Takahashi (Waseda University) at Tokyo, Japan, in 1991. The Berlin conference attracted 120 participants from 19 different countries, representing the most active scientific groups of the world in this field. Since 1982 the field has benefited from the development of lasers with shorter pulses and of reliable tunable light sources in the infrared. Now, the main activities are focused on the primary photo-induced processes and their excited-state dynamics and on detailed investigations in photochemistry and photobiology. The high quality of the contributions given at this conference is reflected in this proceedings volume and will provide all scientists interested in this field with current state-of-the-art results.

For more than two decades time-resolved vibrational spectroscopy (TRVS) was only part of general conferences on solid-state physics, molecular spec troscopy, photochemistry and photobiology. It was in 1982 when the first meeting on TRVS was organized at Lake Placid. The conference met a strong need among the workers in the field, and it was decided to continue with spe cial conferences on this topic. The 2nd International Conference on Time-Resolved Vibrational Spec troscopy was held June 3-i, 1985 at Bayreuth-Bischofsgrun, Germany. Sci entists from many disciplines came together to discuss their common interest in time-resolved techniques and spectroscopic applications. The high qual ity of the research presented, the enthusiasm of the participants, and the attractive surroundings combined to an enjoyable atmosphere. Ample time for discussions and the limited number of participants (approximately 100) stimulated the formal and informal exchange of ideas. "\'umerous people helped to make the conference run smoothly. Special thanks are due to Mrs. Lenich for making the technical arrangements, and to the program committee for the selection of the scientific presentations. The meeting has benefited from several financial souces. The generous sup port by the Emil-Warburg-Stiftung was particularly helpful. Financial aid of the "Deutsche Forschungsgemeinschaft" and of the "Bayerisches Staatsmini sterium fur U nterricht und K ultus" is also gratefully acknowledged.

The advent of laser-based sources of ultrafast infrared pulses has extended the study of very fast molecular dynamics to the observation of processes manifested through their effects on the vibrations of molecules. In addition, non-linear infrared spectroscopic techniques make it possible to examine intra- and intermolecular interactions and how such interactions evolve on very fast time scales, but also in some instances on very slow time scales. Ultrafast Infrared Vibrational Spectroscopy is an advanced overview of the field of ultrafast infrared vibrational spectroscopy based on the scientific research of the leading figures in the field. The book discusses experimental and theoretical topics reflecting the latest accomplishments and understanding of ultrafast infrared vibrational spectroscopy. Each chapter provides background, details of methods, and explication of a topic of current research interest. Experimental and theoretical studies cover topics as diverse as the dynamics of water and the dynamics and structure of biological molecules. Methods covered include vibrational echo chemical exchange spectroscopy, IR-Raman spectroscopy, time resolved sum frequency generation, and 2D IR spectroscopy. Edited by a recognized leader in the field and with contributions from top researchers, including experimentalists and theoreticians, this book presents the latest research methods and results. It will serve as an excellent resource for those new to the field, experts in the field, and individuals who want to gain an understanding of particular methods and research topics.

The work contained in this volume is representative of the presentations made by the participants at the Fifth International Conference on Time-Resolved Vibra tional Spectroscopy, which was held at Waseda University, Tokyo, Japan, from June 3 to 7, 1991. The conference was the fifth in a biennial series initiated in 1982 by Prof. George H. Atkinson (University of Arizona) at Lake Placid, USA, and subsequently convened by Prof. Alfred Laubereau (University of Bayreuth, Germany) and Dr. Manfred Stockburger (Max-Planck Institut, G6ttingen, Ger many) at Bayreuth-BischofsgrUn, Germany, in 1985, by Prof. Joop D.W. Van Voorst (University of Amsterdam) at Amersfoort, The Netherlands, in 1987, and by Prof. Thomas G. Spiro (princeton University) at Princeton, USA, in 1989. The purpose of the conference is to bring together researchers from various disciplines and provide a forum for discussion of the latest advances in time resolved spectroscopies concerned with transient vibrational phenomena and their application to fundamental scientific and engineering studies. The 167 registered participants, including 46 students, from 14 different countries, represented a wide range of scientific disciplines, and clearly indicated that the field continues to expand into new areas of physics, chemistry, biology, and materials science. Their enthusiasm and the originality and quality of the contributions presented produced a very successful and enjoyable conference.

This concise and carefully developed text offers a reader friendly guide to the basics of time-resolved spectroscopy with an emphasis on experimental implementation. The authors carefully explain and relate for the reader how measurements are connected to the core physical principles. They use the time-dependent wave packet as a building block for understanding quantum dynamics, progressively advancing to more complex topics. The topics are discussed in paired sections, one discussing the theory and the next presenting the related experimental methods. A wide range of readers including students and newcomers to the field will gain a clear and practical understanding of how to measure aspects of molecular dynamics such as wave packet motion, intramolecular vibrational relaxation, and electron-electron coupling, and how to describe such measurements mathematically.

Modern Vibrational Spectroscopy and Micro-Spectroscopy: Theory, Instrumentation and Biomedical Applications unites the theory and background of conventional vibrational spectroscopy with the principles of microspectroscopy. It starts with basic theory as it applies to small molecules and then expands it to include the large biomolecules which are the main topic of the book with an emphasis on practical experiments, results analysis and medical and diagnostic applications. This book is unique in that it addresses both the parent spectroscopy and the microspectroscopic aspects in one volume. Part I covers the basic theory, principles and instrumentation of classical vibrational, infrared and Raman spectroscopy. It is aimed at researchers with a background in chemistry and physics, and is presented at the level suitable for first year graduate students. The latter half of Part I is devoted to more novel subjects in vibrational spectroscopy, such as resonance and non-linear Raman effects, vibrational optical activity, time resolved spectroscopy and computational methods. Thus, Part 1 represents a short course into modern vibrational spectroscopy. Part II is devoted in its entirety to applications of vibrational spectroscopic techniques to biophysical and bio-structural research, and the more recent extension of vibrational spectroscopy to microscopic data acquisition. Vibrational microscopy (or microspectroscopy) has opened entirely new avenues toward applications in the biomedical sciences, and has created new research fields collectively referred to as Spectral Cytopathology (SCP) and Spectral Histopathology (SHP). In order to fully exploit the information contained in the micro-spectral datasets, methods of multivariate analysis need to be employed. These methods, along with representative results of both SCP and SHP are presented and discussed in detail in Part II.
