✦ Synopsis

The laser excitation spectrum of the Br,+ molecular ion was observed at rotational resolution for the first time, with the ions being generated by Penning ionization. In contrast to Cl: and F2+ but in agreement with recent theoretical work, no vibrational or rotational perturbations are observed. The data from a number of vibrational bands are fitted simultaneously to give reliable estimates of the Dunham rotational and vibrational constants. This tit indicates that the vibrational numbering used in previous studies should be increased by 1 in the upper state.

The A 2 ⌸-X 2 ⌺ ϩ transition of 174 Yb 35 Cl and 172 Yb 35 Cl has been rotationally analyzed for the first time. Doppler-limited laser excitation spectroscopy with selective detection of fluorescence was used to obtain spectra of the 0 -0 and 1-0 bands with a measurement accuracy of approximately 0.
