✦ Synopsis

Five vibrational progressions associated with transitions to Rydberg states in molecular bromine are reported in the region 68000 to 73 400 cm-' (8.5 to 9.1 eV). These Rydberg states are accessed by two-photon absorption, and subsequently ionised by a photon of the same frequency. The photoelectron spectra of these states reveal unperturbed Rydberg character, and unambiguously allow the vibrational assignment of the Rydberg progressions and the determination of the convergence limit (i.e. the core) of these Rydberg states. The values obtained for the origin and the cores of the Rydberg states are 68 825 cm-' (ZIIax,z), 70 568 cm-' (211r,,2), 71750 cm-' ('II,,,,), 72440 cm-' (211s,,2), 72904 cm-' (2fI1s,2). Evidence for perturbations in a few vibrationally oacited Rydberg states is found in the photoelectron spectra.
