Aa. Kosterev et al., ULTRAFAST COLLISIONAL REDISTRIBUTION OF VIBRATIONAL-ENERGY IN SMALL POLYATOMIC-MOLECULES, Journal of molecular structure, 349, 1995, pp. 231-233
The rate constants of energy relaxation are measured for high-frequenc
y vibrations in CHF3 and CHF2Cl in gas phase. The obtained values are
extraordinarily high for V-V' exchange. The measurements carried out i
n gas mixtures with different buffer gases unambiguously show a predom
inant role of collision-induced intramolecular redistribution.
