Raman Effect of Benzene and Toluene Under High Dispersion and Resolving Power

This paper is a report of work carried out at the Macdonald Physical Laboratory on the Raman effect of benzene and toluene. The six-prism spectrograph, used by Dr. J. S. Foster for his work on the Stark effect, was employed in the investigation. It was found that a number of entirely new lines were observed in the Raman spectrum of both liquids. Some of these are due to the separation into components of previously observed lines; others are entirely new. Accurate measurements are given of the Raman frequency shifts and comparison with other results is afforded.
