Multiphoton dissociation of CF/sub 3/Cl and CF/sub 3/Br under CO/sub 2/ laser pulses
Description
Multiphoton dissociation of CF/sub 3/Cl and CF/sub 3/Br induced by CO/sub 2/ laser pulse has been studied in the (0.1 - 60 torr) pressure range and (5 - 30 Joule/cm/sup 2/) average energy density range. The laser was adjusted on 1071.9 cm/sup -1/ and 1052.2 cm/sup -1/, resp., so as to excite preferentially the /sup 13/C isotopic molecules. The effects of pressure and energy on the isotopic selectivity were measured and a remarkable difference was found between the two molecules. As for the dissociation probabilities, they vary exponentially with the inverse of the energy. The applicability of such an Arrhenius-type relation is discussed and semi-quantitatively justified
