ABSTRACT
The quantum scattering theory of resonant two-photon (ω1+ω2) dissociation is developed and applied to Na2 photodissociation. In the energy range considered, photodissociation primarily occurs via excitation to the A 1Σu state, intersystem crossing to the b 3Πu state, and subsequent excitation to the triplet continuum. Photodissociation rates to produce Na(3s)+Na(3d), Na(3s)+Na(4s), and Na(3s)+Na(3p) are reported as a function of both ω1 and ω2. Characteristic features due to spin–orbit coupling and to multiple product production are observed and discussed.
