Raman probing of overtone and combination bands to study the vibrational energy distribution produced by multiple-photon excitation

Vibrational energy distribution in CF 3Br, produced by multiple-photon excitation, is studied with the use of Raman probing of fundamental bands and also overtone and combinations bands. On a collision-free time scale, statistical energy distribution among vibrational modes is found at energies over...

Description
Summary:Vibrational energy distribution in CF 3Br, produced by multiple-photon excitation, is studied with the use of Raman probing of fundamental bands and also overtone and combinations bands. On a collision-free time scale, statistical energy distribution among vibrational modes is found at energies over 7200 cm −1. Possible physical causes of this effect are discussed.
