Abstract

The photoelectron spectra obtained following three photon resonant, four photon ionization of H2 via the B′ 1Σ+u, v=0–2 and via the D 1Πu, v=0, 1 resonant intermediate levels are presented. The intensity ratios of the photoelectron peaks agree qualitatively with the Franck–Condon factors calculated for ionization from the resonant intermediate levels. However, the quantitative agreement is rather poor. Alternative mechanisms for the observed non-Franck–Condon behavior are pointed out, but assessment of their relative importance requires detailed calculations.
