| Abstract: | Vibrational energy distribution in CF3Br, 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. |
