High resolution emission spectra of H2 and D2 near 80 nm

2014 A few lines have been observed in the far ultraviolet emission spectrum of molecular hydrogen and deuterium. They are assigned to transitions from levels of the 3p03C0D 103A0 ustate, lying above the dissociation limit into H(ls) + H(n = 2), near 84.5 nm, and, for some of them, above the first ionization limit near 80.4 nm, the lower state being X 103A3g+ (v" = 1). This is in fair agreement with measured predissociation and preionization yields. Accurate line position measurements lead to molecular constants in very good agreement with theoretical calculations.
