The laser Raman scattering technique shows potential as a diagnostic method for determining the chemical and thermodynamic state of high-temperature gases. To investigate the utility of this technique for shock-tube diagnostics, and to validate the method at known elevated temperatures, vibrational Raman intensities were measured behind an incident shock wave. Intensity history data through the wave front, vibrational excitation times of oxygen in air, along with temperature and density measurements for oxygen and nitrogen in air were obtained over a range of postshock conditions. The measured densities and temperatures were found to be in good agreement with shock-wave theory. An excitation time measurement also agreed well with shock-tube data obtained with other diagnostic methods. In general, the results indicated that the Raman scattering technique was accurate at elevated temperatures and should prove useful in determining the thermochemical state of gases in continuous flows as well as in shock tubes and other impulse facilities.

Bringing together scattered literature from a range of sources, Laser Spectroscopy and ItsApplications clearly elucidates the tools and concepts of this dynamic area, and providesextensive bibliographies for further study.Distinguished experts in their respective fields discuss resonance photoionization, laser absorption,laser-induced breakdown, photodissociation, Raman scattering, remote sensing,and laser-induced fluorescence. The book also incorporates an overview of the semiclassicaltheory of atomic and molecular spectra.Combining background at an intermediate level with an in-depth discussion of specifictechniques, Laser Spectroscopy and Its Applications is essential reading for laser and opticalscientists and engineers; analytical chemists; health physicists; researchers in optical,chemical, pharmaceutical, and metallurgical industries. It will also prove useful for upperlevelundergraduate and graduate students of laser spectroscopy and its applications, andin-house seminars and short courses offered by firms and professional societies.

Volume 8 in the series Progress in AnaZyticaZ Chemistry presents a selection of the papers given at the 1975 Eastern Analytical Symposium. The analytical chemist is under constant pressure not only from the research chemist whose sampIes he must characterize and control, but also from an ever-increasing group of governmental agencies stimulated by public concern over health and environmental problems, to determine the most sophisticated kinds of compounds as lower and lower levels. The subjects covered in these papers are wide-ranging, from the analysis of incinerator effluents to the determination of drugs in blood, but through them runs a common theme, the appli cation of the latest instrumental techniques to the problems of analysis. The authors show how successful they have been in rising to the analytical challenges pre sented by an increasingly complex world. The editors take this opportunity to thank them for their efforts in producing such excellent papers for publication in so short a time. Dur special appreciation goes to Dr. M. W. Miller, who acted as program chairman, and his team of session chairmen: P. R. Brown, L. J. Cline Love, C. Horvath, J. R. Lindsay, and T. C. Rains.
