Infrared Laser Spectroscopy of Transient Species,ns and many free radicals (e.g., C.) have infrared electronic transitions. Vibrational transitions have characteristic frequencies and carry chemical group information in a way that rotational and electronic transitions do not.

Sources and Instrumentation for Laser Spectroscopy,92; Demtröder, 1982) and increasingly in general spectroscopy texts (.. Hollas, 1998) demand sophisticated laser systems. While, of course, central to these systems is the laser source itself, ancillary instrumentation for the measurement of optical power and its distribution in frequency, time and

One of the most influential early investigations into light scattering was undertaken by Lord Rayleigh (1899). In this study it was shown that the intensity of e
