BROADENING AND SHIFTING OF THE DEPOLARIZED COMPONENT OF THE RAMAN Q-BRANCH IN D-2 AT ROOM-TEMPERATURE

We report the first direct measurement of the broadening and shifting of the depolarized component of the Raman Q branch in D-2. Spectral da ta were recorded from 1.5 to 12 amagat at 305.2 K. Both the measured b roadening and shifting of the depolarized component are significantly different from that for the polarized Q branch. These results can be u sed as a check of theoretical calculations when they become available. Here they are used to correct previously reported values of the broad ening of the polarized part of the e-branch spectrum. Measured values of the ratio of the depolarized to polarized intensity for the Q-branc h lines are also given.
