✦ Synopsis

Reaction of electronically excited oxygen atoms with HCI yields highly vibralionally and rotationally excited OH displaying the propensity for II(A' ),I sublevel production characteristic of reactions in which the rotation plane of the OH product coincides with the plane of a triatomic intermediate complex. Because the rotational distribution differs significantly from that expected from direct HLH' abstraction, the reaction probably proceeds via the HOCI( 'A') surface that favors formation of the OH diatomic. The vibrational distribution agrees with that previously observed by infrared chemiluminescence; earlier observation of OH( X*lI) using LlF could not be confirmed.
