Abstract
Collision-induced spin-orbit relaxation in a vibronically excited stat e CO+ A2PI1/2(upsilon=1)+He-->CO+ A2PI3/2(upsilon=1)+He has been inves tigated by using a flowing afterglow/time-resolved LIF technique. The rate constants k12(2PI1/2-->2PI3/2) and k21 (2PI3/2-->2PI1/2) are dete rmined to be k12+k21 = (3.0 +/- 0.3) X 10(-10) cm3 molecule-1 s-1. A c omparison of the results with those for the neutral system NO X2PI(ups ilon=0)+He suggests that neither the positive charge on the ion nor th e vibrational energy plays significant roles in the fast spin-orbit re laxation process.
