The excimers are formed via a photochemical reaction between H2(C 'II., B 'XL) and rare gases following excitation with synchrotron radiation. Broad fluorescence continua in the near UV are observed and assigned to the rare gas hydride transition B *II +X 'Z +. In the case of NeH, the A *Z + state also contributes to the fluorescence spectrum. Experimentally derived binding energies for the B state and bound-free spectra of HeH and ArH are in good agreement with recent ab initio calculations. Radiative lifetimes, quenching cross sections and formation cross sections have also been determined.

The bound-free emission of a mass-selected molecular beam of helium hydride has been investigated. Excited molecules were produced by electron transfer to helium hydride ions. The study of different isotopic mixtures and lifetime measurements support the assignment B 2 ll + X 2 Z+ for the observed b
