Tóm tắt

Using high resolution spectrograms, the broadened linewidths for several bands of the B2Sigma+-A2Sigma+system of OD have been reinvestigated. Comparison between observed and calculated halfwidths shows that the high-vibrational level predissociation is a case c+one, due to a first order spin orbit interaction, with a repulsive4Pi state which crosses the A2Sigma+state of OD at r=1.65 AA between v=7 and v=8, and between v=5 and v=6 for OH. The vibration- rotation interaction is shown to be responsible for the strong halfwidth dependence on the rotational quantum number.
