Abstract
The band oscillator strength of OH was found to be essentially independent of rotational excitation for the (1,0) transitions, but to decrease with rotation for the (0, 0) transitions. This difference in the rotational dependence is a result of competition between a rotationally induced decrease in the electronic transition moment and rotationally induced changes, which may be either an increase or decrease, in the Franck-Condon factor for these bands.Keywords
