✦ Synopsis

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 lo5 molecules/cm3 per quantum state is achieved.

The Born-Oppenheimer energies have been computed for the C al-Iu state of H 2 by the variational method in the interval 0.8 ~< R ~< 12 a o and the electronic transition moments for the Werner band determined. The energies are by a few hundredths of a wavenumber lower than ever reported and the compu
