Abstract
A theoretical study of field‐induced predissociations is presented. It is found that the rate of predissociation in general depends on the rotational quantum number. However, for several limiting cases the rotational dependence cancels out. The vibrational effect on predissociation is treated in the semiclassical approximation. Comparison is made with the recent experimental results on the magnetic quenching of iodine fluorescence by Degenkolb, Steinfeld, Wasserman, and Klemperer.
