Abstract
A new method of detecting vibration-rotation transitions in the HD+ ion is described. The technique uses an ion beam and relies upon the detection of infrared photodissociation of levels close to the dissociation limit of HD+. These levels are populated by the electron impact ionization process and measurements of nine rotational components of the v = 18-16 band are described. The results reveal small but systematic discrepancies in the best available theoretical values of the relative energies of these vibration-rotation levels. The resolution of structure arising from proton hyperfine interaction is also described.Keywords
