✦ Synopsis

In the paper, we compare the results of our ab initio calculations for the ro-vibrational branching ratios resultmg from a (3 + 1) REMPI of H, via the B 'X: state with the experimental data of Pratt, Poliakoff. Dehmer and Dehmer. These results indicate that non-Franck-Condon effects are less important here than in the (3+ 1) REMPI of H, via the C'H, state. We observe that the AJ= &3 peaks in the photoelectron spectrum are of negligible strength and that the ratio of AJ= +1 to A J = -1 peak is independent of the ionic vibrational state. A detailed analysis indicates that these features arise as a result of a dynamic interference between the da and dn ionization channels and do not imply either the smallness of the d-wave or the smallness of the j, = 3 angular momentum coupling terms.

It is shown that there are some advantages to determining ground state population distributions of H2 by 1 + 1 REMPI using the C 'II, (u' ~0) state as the intermediate state. The state distribution can be deduced more directly from the ion signal, in addition, a much improved sensitivity of < I .7x
