Abstract
In connection with our program of investigation on relaxation processes in liquids, including vibrational and rotational relaxation in particular, we have been evaluating measurements of Infrared band shapes for the calculation of the correlation function and have begun to employ Raman observations along with the infrared band shapes to obtain information on the relaxation processes. In particular, we have sought to obtain the most accurate band shapes possible, so that the resulting Fourier transforms may be as reliable as possible in their details. We have applied these methods, both Raman and infrared, to chlorobenzene, fluorobenzene, iodobenzene, pyridine, and their perdeutero isotopes. These constitute an interesting set of related molecules whose rotational and vibrational dynamics may be expected to be reasonably ""normal."" In connection with the experimental technique and the reduction of data, some discussion will be presented regarding the difficulties of significant or variable ""base lines"", and methods of minimizing these problems.
