THE INFRARED AND RAMAN ROTATION-VIBRATION BAND CONTOURS OF 1,3,5-TRIFLUOROBENZENE-$d_{3}$

$^{1}$ H. F. Shurvell, T. E. Cameron, D. B. Baker, and S. J. Daunt, Spectrochim. Acta (1979), in press.Author Institution:Infrared and Raman band contours of gaseous 1,3,5-trifluorobenzene-$d_{3}$ and Raman band contours of gaseous 1,3,5-trifluorobenzene have been recorded under moderate resolution. First order Coriolis constants have been calculated for the infrared and Raman active $E^{\prime}$ fundamentals using computer simulation of the contours. Coriolis constants of the Raman active $E^{\prime\prime}$ fundamentals are also reported and compared to those predicted in an earlier $study^{1}$. Several infrared overtone and combination bands of $E^{\prime}$ symmetry of the deuterated trifluorobenzene have been simulated and the ``effective’’ Coriolis constants determined. Agreement between observed values of $\zeta^{z}_{eff}$ and the values predicted from $\zeta^{z}_{i}$ constants of the constituent degenerate fundamentals is fairly good. The assignments of the overtone and combination bands of both molecules have been reexamined
