Studies of vibrational relaxation in CDF following intense laser excitation.

The V-T/R relaxation time of CDF was measured studying the laser-induced infrared fluorescence emitted by vibrationally excited CDF. Following excitation by the 10 R(12) line of a TEA CO laser infrared fluorescence has been detected without spectral resolution in the 1100-700 cm range. A decay rate of 28.8 ms Torr was obtained for pure CDF when it is excited with a fluence of 390 mJ/cm. Measurements have also been made in the presence of different bath gases (He, Ne, Ar, Xe, and CHF). [ABSTRACT FROM AUTHOR]
