The removal of DF (v=3 and 4) by H and D atoms
Abstract
The deactivation rate coefficients for the removal of DF (v=3) and DF (v=4) by H and D atoms have been measured at 295 K by the technique of laser-induced fluorescence in a discharge flow-tube apparatus. The rate coefficients were found to increase dramatically with vibrational level v. Data obtained for the removal of DF (v=4) in the presence of H atoms have been used to infer a rate coefficient of (4.5±2)×1011 cm3/mol s for the reaction H+DF (v=4)→HD+F. This is in good agreement with a value calculated from the equilibrium constant and a previous measurement of the F+HD rate coefficient obtained by Berry.
