N2 - We present energy and angular distributions of photoelectrons from the resonant two-photon, two-color ionization of sodium dimer through particular rovibronic levels of the B 1Πu and A 1Σ+u state. The vibrational state distributions of the ion core produced from the B state do not correspond to Franck-Condon distributions, according to the photoelectron energy spectra. Non-Franck-Condon distributions of final states were observed at two ionizing wavelengths, and through all the four intermediate rovibrational levels of the B state studied here. Ionization through the A state showed a Franck-Condon-like distribution of final states. At best, plausible conjectures can be suggested to account for the non-Franck-Condon behavior of the B state.
