Optoacoustic Spectroscopy and Detection discusses the fundamental principles and practice of optoacoustic spectroscopy. This book serves as a basis for evaluation of the feasibility of using such techniques in specific instances. Organized into eight chapters, this book starts with an overview of the detection and identification of gas contaminants, which is necessary to understand the physical description of the generation and measurement of the optoacoustic signal. This text then provides an understanding of the optoacoustic effect on a molecular scale and describes the energy transfer processes and estimates of the lifetimes of vibrationally excited states. Other chapters consider the options available to the researcher in the selection of optoacoustic system design. This book discusses as well the capabilities and limitations of various optoacoustic system designs. The final chapter deals with the technique used for exploring the absorption spectra of substances, including powders, gels, adsorbed films, and organic tissues.
This book is a valuable resource for researchers and graduate students engaged in the study of optoacoustic spectroscopy.
