In this paper, we report the results of ab initio calculations of photoelectron angular distributions and vibrational branching ratios for the (2+1) REMPI of H/sub 2/ via the E,F /sup 1/..sigma../sup +//sub g/ state, and compare these with the experimental data of Anderson et al. (Chem. Phys. Lett. 105, 22 (1984)). These results show that the observed non-Franck--Condon behavior is predominantly due to the R dependence of the transition matrix elements, and to a lesser degree to the energy dependence. This work presents the first molecular REMPI study employing a correlated wave function to describe the Rydberg--valence mixing in the resonant intermediate state.
