✦ Synopsis

Laser excitation spectra of the lowest vibrational levels, v" = 2-5 and v' = 0-4, for the Bi2 X1Sigma+g --> A(0(+)u) system have been recorded for a wide range of rotational levels, 0 < J < 211, at Doppler-limited resolution of 0.013 cm-1. New rotational term values and spectroscopic constants are reported, improving the accuracy of predicted line positions for high rotational levels by as much as 0.8 cm-1. In addition, Franck-Condon factors are computed and compared with experimental observations from CW laser-induced fluorescence spectra.
