Abstract
The photodissociation of Na2 has been investigated in a molecular beam experiment. The velocity and angular distribution and internal states of the fragments were determined by Doppler spectroscopy. Three different photodissociation processes were observed and identified: direct photodissociation by excitation from the X 1Σg + ground state to the dissociation continuum of the B 1Πu state, dissociation of quasibound levels of the B state, and induced two‐photon dissociation of Na2 leading to Na*(nl) fragments. Direct dissociation of the B 1Πu state yields only Na*32 P3/2 fragments, which does not support the interpretation of reported 2P3/2 and 2P1/2 fragment emission.
