A Raman spectroscopic study of a vibration‐vibration near resonant energy transfer mechanism in liquid toluene‐ d 5

The polarized signals from the methyl group stretching coordinate of toluene‐ d 5 have been analyzed by the time correlation technique. Based upon the polarized signal correlation function of the 2922 cm −1 signal and the presence of Fermi resonance in the molecule, mechanistic interpretations of a vibrational internal conversion process are offered.
