Volume 7 of Developments in Applied Spectroscopy is a collection of forty-two papers selected from those that were presented at the 7th National Meeting of the Society of Applied Spectroscopy, held (in place of the 19th Mid-America Symposium on Spectroscopy) in Chicago, May 13-17, 1968. These papers, selected by the editors and reviewed by persons knowledgeable in the field, are those of the symposium type and not those pertaining to specific research topics that one would expect to be submitted to a journal. It is the opinion of the committee that this type of publication has an important place in the literature. The relatively large number of papers would result in quite a sizable volume if bound in one set of covers. For this reason, and to present the material in areas of more specific iilterest, Volume 7 was divided into two parts, Part A, Physical-Inorganic, and Part B, Physical-Organic Developments. The 7th National Meeting was sponsored by the Chicago Section as host in cooperation with the St. Louis, New England, Penn York, Niagara-Frontier, Cincinnati, Ohio Valley, New York, Baltimore-Washington, North Texas, Rocky Mountain, and Southeastern Sections of the Society for Applied Spectroscopy and the Chicago Gas Chromatography Group. The editors wish to express their appreciation to the authors and to those who helped with the reviewing. The latter include Dr. Elma Lanterman, Mr. John E. Forrette, Dr. Carl Moore, Dr. B. Jaselskis, Mr. H. G. Zelinski, Mr.

For the last thirteen years, the Chicago Section of the Society for Applied Spectroscopy has sponsored a symposium in the spring of each year. In this span, the symposia have shown a steady increase in attendance, in the number of papers presented, in the number of sessions, and in the number of days the conference lasted. The duration of the most recent sym posium was four days, with sessions devoted to molecular spectroscopy, including infrared, Raman, ultraviolet, and visible, and to X-ray, NMR, emission, and flame spectroscopy, respectively, with a special session devoted to gas chroma tography because of its growing interest in applied spectro scopic work. Another feature of this last symposium was the attempt on part of the Symposium Committee to establish and maintain the scientific level at that of applied physics. This should place the present symposium at a level somewhere between that of the Ohio State symposium and that of the Pittsburgh meeting, thus approaching the level of applied chemical physics. In addition, the symposium was designed to offer to sci entists from other disciplines and students an opportunity to attend introductory panels and lectures and at the same time the mature investigators a meeting ground and the chance to keep abreast of the latest developments in spectroscopy. How well these aims have been accomplished is best attested to by the phenomenal growth of the symposium.

Spectroscopy in its broadest sense deals with the interaction of light with matter. Spectroscopic techniques contribute a lot to various diverse research areas including material processing and characterisation, communication, forensic science, defence, etc. The rapid expansion of research activity in the field of material science evokes the need for different analytical and diagnostic techniques. Spectroscopy is such an analytical and diagnostic tool, extremely used to characterise materials. It is now commonly used by astrophysicist, mineralogists, nano-physicists or even scientists working in medical research. This book has therefore been prepared to provide easy access to basic information on different spectroscopy techniques and related instrumentation. This book is intended as a guide to the novice reading technical books or facing the complexities while dealing with the concept of spectroscopic techniques and their instrumentation. The authors of chapters presented in this book are all experts in their fields and were instructed to give substantial information to enable novices to learn and understand the advanced spectroscopic techniques. The present book primarily provides details about the time resolved spectroscopy; laser induced breakdown spectroscopy (LIBS); Raman spectroscopy; nonlinear spectroscopy; microwave spectroscopy; up conversion spectroscopy, etc

This book delineates practical, tested, general methods for ultraviolet, visible, and infrared spectrometry in clear language for novice users, and serves as a reference resource for advanced spectroscopists. Applied Spectroscopy includes important information and equations which will be referred to regularly. The book emphasizes reflectance and color measurements due to their common usage in todays spectroscopic laboratories, and contains methods for selectinga measurement technique as well as solar and color measurements. Written by experts in the field, this text covers spectrometry of new materials, ceramics, and textiles, and provides an appendix of practical reference data for spectrometry. - Book topics include: Practical aspects of spectrometers and spectrometry; Sample preparation; Chemometrics and calibration practices; Reflectance measurements; Standard materials measurements - An emphasis is placed on reflectance and color measurements due to their common usage in today's spectroscopic laboratories - Methods for selecting a measurement technique are included as well as solar measurements and reference information on sources, detectors, optical fiber and window materials
