Vibrational relaxation in the HF–HCl,HF–HBr,HF–HI, and HF–DF systems

The laser-excited fluorescence method has been employed to determine rate constants for vibrational energy transfer (V → V, R) and deactivation (V → R, T) processes in the HF–HCl,HF–HBr,HF-HI, and HF–DF systems at temperatures of 300 and 350°K. The rates exhibit a marked inverse temperature dependen...

Description
Summary:The laser-excited fluorescence method has been employed to determine rate constants for vibrational energy transfer (V → V, R) and deactivation (V → R, T) processes in the HF–HCl,HF–HBr,HF-HI, and HF–DF systems at temperatures of 300 and 350°K. The rates exhibit a marked inverse temperature dependence indicative of strong attractive (hydrogen-bonding) intermolecular forces. Energy transfer from HF to HI appears to occur by a double vibrational quantum transition in HI.
