Notes:
PUMP–DUMP–PROBE experiments were performed on nitric oxide (NO) in order to study the rotational and spin–orbit energy transfer in a highly vibrationally excited diatomic. Total depopulation as well as state-to-state rotational and spin–orbit energy transfer rate constants were measured for v=8 and 19 of the ground electronic state. By comparing this new set of results with previously measured results for v=2 [Aa. Sudbo and M. M. T. Loy, J. Chem. Phys. 76, 3646 (1982)] the vibrational influence on the rotational and spin–orbit energy transfer dynamics could be evaluated. Total depopulation rate constants for individual rovibrational states were found to be very similar for v=2, 8, and 19. State-to-state rotational energy transfer rate constants could be compared for v=8 and 19, and again only small differences were found. It appears that vibrational energy does not have a significant impact on the rotational and spin–orbit energy transfer dynamics for NO–NO collisions.
