The gas phase Raman band contours of 1,3,5-trifluorobenzene and the infrared and Raman band contours of 1,3,5-trifluorobenzene-d3

Abstract The gas phase infrared and Raman spectra of 1,3,5-trifluorobenzene- d 3 has been recorded. The gas phase Raman spectrum of 1,3,5-trifluorobenzene- h 3 has also been recorded. Computer simulations of the band contours of the degenerate vibrational modes have been used to determine the first-order Coriolis coupling constants for both molecules. The ζ z values were then compared with those evaluated from force field calculations.
