โœฆ Synopsis

The vibration to translation (VT) relaxation rates of laser excited CF,HCl+argon mixtures have been measured by means of an interferometric method. Approximately exponential signals have been observed for neat CF,HC1 and CFI HCl-rich mixtures, while for Ar-rich mixtures the interferometric signals are clearly non-exponential. For a given Ar fraction the VT rates have been found not to be additive. Deviations from the linear mixture rule are more evident for higher initial vibrational excitations of the relaxing molecules.

The deexcitation of HCl( u= 1) in the HIO-HCl interaction is studied at thermal collision energies using classical trajectory techniques. In the presence of strong attraction, the collision partners form a complex, and the initial vibrational energy flows freely among various internal modes in the c
