Abstract
The photodissociation cross sections corresponding to absorption from the ground electronic state X 1 Σg+ of H2 into the continua of B 1 Σu+, C 1 Πu, and B’ 1 Σu+ systems were calculated using accurate ab initio potential-energy and dipole-moment values. Noticeable discrepancies were found with previous calculations. Adiabatic corrections and centrifugal distortion were taken into account.
