The B²Σ+ - X²Σ+ System of Sr79 and Sr81Br: Rotational and Vibrational Analysis

Research output: Contribution to journal › Article › peer-review

Abstract

Doppler-free laser polarization spectroscopy has been used to record the (0, 0), (1, 1), and (2, 2) bands of the B2Σ+-X2Σ+ system for both Sr79Br and Sr81Br. With the help of microwave labeling and additional band selective detection of the laser-induced fluorescence a rotational analysis could be performed. The optical data were combined with the results of independent microwave measurements of the X2Σ+ state in a weighted least-squares fit. Local perturbations were observed in each vibrational state of B2Σ+. Bandhead positions of Δv = ±1 bands were used for the vibrational analysis.
