The vibration to translation (VT) relaxation rates of laser excited CF2HCl + argon mixtures have been measured by means of an interferometric method.

Abstract
The vibration to translation (VT) relaxation rates of laser excited CF2HCl + argon mixtures have been measured by means of an interferometric method. Approximately exponential signals have been observed for neat CF2HCl and CF2HCl-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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
