Observation of nonequilibrium vibrational distribution in infrared multiphoton excitation of molecules by Raman spectroscopy.
Raman scattering is applied to the study of energy distribution during multiphoton excitation of molecules. The existence of two ensembles-hot and cold molecules-is shown. The fraction of the excited molecules in the upper ensemble is measured for SF(6) and CF(3)I.
