Description
Summary:Author Institution: Science Institute, University of Iceland, Dunhagi 3, 107 Reykjavík, Iceland Mass spectra are recorded for one-colour (2 + n) resonance enhanced multiphoton ionization (REMPI) of HX (X = Cl , Br) as a function of resonance excitation energy to obtain two-dimensional REMPI data. Perturbations due to Rydberg to ion-pair state interactions show as line shifts, ion signal intensity variations as well as band width broadenings depending on rotational quantum numbers, J$ ^{\prime }$. The data allow determination of parameters relevant to the nature and strength of state interactions as well as dissociation and ionization processes. Alterations in X$^{+}$ and HX$^{+}$ signal intensities prove to be very useful for spectra assignments.
