Abstract

Molecular chlorine was photodissociated at 310 and 330 nm using circularly polarized light. Orientation moments of the electronic angular momentum of product ground-state Cl(2P3/2) and excited-state Cl*(2P1/2) chlorine atoms were measured and the contributions from both coherent and incoherent dissociation mechanisms were resolved. The experimental results for Cl* can be explained by nonadiabatic transitions from the C 1Π1u state to higher states of 1u symmetry, induced by noncrossing-type radial derivative coupling.
