The vibrationally mediated photodissociation dynamics of HF and DF, following A 1Π←X 1Σ+electronic excitation, are examined using time-dependent wave packet techniques. Predictions of the branching fraction for the formation of excited state fluorine, F(2P1/2), are made for a wide range of excitation energies and for the initial vibrational states v=1, 2, and 3. The preceding article (Ref. 33) discusses the underlying theory and presents results for photodissociation from the ground vibrational state (v=0). The calculated branching fraction for HF photodissociation from the v=3vibrational state agrees well with the value of 0.42±0.03 measured experimentally at 193.3 nm by Zhang et al. [J. Chem. Phys. 104, 7027 (1996)]. The results are discussed in context with the corresponding results for HCl and DCl.
