We report multichannel quantum defect theory calculations of vibrational branching ratios and photoelectron angular distributions for photoionization of an ortho/para equilibrium mixture of H2 at 300 K, between wavelengths 762.5 and 765.0 Å. We compare our results with the recent synchrotron measurement of these observables by Dehmer et al. [J. Chem. Phys. 97, 7911 (1992)], and the total photoionization cross sections measured by Dehmer and Chupka [J. Chem. Phys. 65, 2243 (1976)]. Except in the region of autoionizing resonances which compete with a dissociation channel, semiquantitative agreement between calculations and experiment is obtained for branching ratios and angular distributions for the v+=0–2 levels, and for the v+=3 branching ratio. However, the level of agreement between the present calculations and the synchrotron measurements is significantly worse than that obtained for the total photoionization cross section.
