title: Observation of nonequilibrium vibrational distribution in infrared multiphoton excitation of molecules by Raman spectroscopy.
abstract: 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.
