COLLISIONAL BEHAVIOR WITH AR OF THE LAMBDA-DOUBLETS OF CH(X(2)PI) N''=15 PRODUCED IN THE 2-PHOTON DISSOCIATION OF CH2CO AT 279.3 NM

Relaxation of the N″ = 15 Λ doublets of CH(X 2Π) produced in the two-photon dissociation of ketene at 279.3 nm has been observed in the presence of Ar. An initially equilibrated nascent Λ doublet population is seen to be removed in such a way that the component of A″ symmetry (π orbital perpendicula...

Description
Summary:Relaxation of the N″ = 15 Λ doublets of CH(X 2Π) produced in the two-photon dissociation of ketene at 279.3 nm has been observed in the presence of Ar. An initially equilibrated nascent Λ doublet population is seen to be removed in such a way that the component of A″ symmetry (π orbital perpendicular to the plane of rotation) dominates. The application of recent theory describing collisions of 2Π diatomics with closed shell atoms is briefly discussed.
