As is often the case, the preface is the last task to be finished during the preparation of a large volume such as you are now holding. The first task, obtaining approval for a symposium on the industrial applications, now seems a long time ago. The idea orginated with John Stevens, probably in 1982, from his observation of papers dealing with industrial applications of the Mossbauer effect appearing in the Mossbauer Effect Reference and Data Journal. His initial suggestion for a symposium entitled "Industrial Applications of the Mossbauer Effect" to be held at a national meeting of the American Chemical Society eventually led to the symposium at the International Chemical Congress of Pacific Basin Societies which met in Honolulu, Hawaii in December 1984. This volume is the result of the symposium at the above mentioned Congress, but is not actually the 'proceedings' of the symposium because this volume does not contain all of the over one hundred Mossbauer effect papers that were pre sented at the symposium. Rather it contains a selection of papers that the or ganizing committee for the symposium deemed most appropriate for a volume devoted to industrial applications of the Mossbauer effect. The final volume also contains six chapters that were not a part of the symposium but which are closely related to the topic. There is another difference from many proceedings.

International research scientists and engineers from academia and industry present details of the most recent investigations on industrially related topics and projects using Mössbauer Spectroscopy as a primary analytical technique. Papers cover a broad range of topics including corrosion, catalysis, and environmental monitoring.

Mössbauer Spectroscopy of Environmental Materials and their Industrial Utilization provides a description of the properties of materials formed on the earth's surface, their synthetic analogs where applicable, and the products of their modifications in the course of natural processes, such as weathering, or in industrial processing as reflected in their Mössbauer spectra. Particular emphasis is placed on the way in which these processes can be observed and elucidated through the use of Mössbauer spectroscopy. The first chapter covers the basic theory of the Mössbauer effect and Chapters 2 and 3 deal with the nuts and bolts of experimental Mössbauer spectroscopy. The principles of these first three chapters, illustrated with many case studies, are applied to different areas of interest in Chapters 4 through 12. The book is directed to a broad audience ranging from graduate students in environmental sciences or chemical engineering with little or no expertise in Mössbauer spectroscopy to researchers from other disciplines who are familiar with this technique but wish to learn more about possible applications to environmental materials and issues.

Mossbauer spectroscopy has proved itself a versatile technique, finding applications in diverse areas of science and industry. Starting from physics and chemistry it spread into biochemistry, mineralogy, biochemistry, corrosion science, geochemistry and archaeology, with applications in industrial and scientific research. The author aims to help advanced university students, professionals and research workers who ask the question "what's in it for us?". After a concise account of experimental techniques, he emphasizes those applications in which there are few, if any, alternative ways of obtaining the same information about electron fields and the nuclei. He explains areas of industrial interest, including the important applications related to tin and iron on which there is much activity in research and development, and interprets the extension of Mossbauer techniques to main group, transitional and other suitable elements. Attention is paid to factors which may lead to misinterpretation of spectra and another chapter covers the complexities of interpreting emission spectra. - Discusses the appearance of Mossbauer spectroscopy in biochemistry, mineralogy, biochemistry, corrosion science, geochemistry and archaeology, with applications in industrial and scientific research - Emphasizes the applications in which there are few, if any, alternative ways of obtaining the same information about electron fields and the nuclei - Attention is paid to the complexities of interpreting emission spectra and the factors which may lead to misinterpretation of spectra

Applications of Mössbauer Spectroscopy, Volume I is a collection of essays that discusses the research performed using Mössbauer spectroscopy. The book presents the effect of some stabilizers of polyethylene. It demonstrates the polymerization processes and structure of catalytically active centers. The text also describes the chemical processes in butyl rubber vulcanization. It discusses the experimental studies of iron transport proteins and the thermal decomposition of solids. The section that follows describes the paramagnetic hyperfine structure. The book will provide valuable insights for scientists, chemists, students, and researchers in the field of organic chemistry.

Two decades have passed since the original discovery of recoilless nuclear gamma resonance by Rudolf Mossbauer; the spectroscopic method based on this resonance effect - referred to as Mossbauer spectroscopy - has developed into a powerful tool in solid-state research. The users are chemists, physicists, biologists, geologists, and scientists from other disciplines, and the spectrum of problems amenable to this method has become extraordinarily broad. In the present volume we have confined ourselves to applications of Mossbauer spectroscopy to the area of transition elements. We hope that the book will be useful not only to non-Mossbauer special ists with problem-Oriented activities in the chemistry and physics of transition elements, but also to those actively working in the field of Mossbauer spectroscopy on systems (compounds as well as alloys) of transition elements. The first five chapters are directed to introducing the reader who is not familiar with the technique to the principles of the recoilless nuclear resonance effect, the hyperfme interactions between nuclei and electronic properties such as electric and magnetic fields, some essential aspects about measurements, and the evaluation of Moss bauer spectra. Chapter 6 deals with the interpretation of Mossbauer parameters of iron compounds. Here we have placed emphasis on the information about the electronic structure, in correlation with quantum chemical methods, because of its importance for chemical bonding and magnetic properties.
