High-Resolution Laser Excitation Spectra of the A2Pi <-- X2Sigma+ System of SrBr: The 0-0 and 1-0 Bands of Sr79Br and Sr81Br.
Two bands (0-0 and 1-0) of the A2Pi-X2Sigma+ system of 88Sr79Br and 88Sr81Br have been analyzed rotationally for the first time. Well-resolved spectra were recorded by laser excitation spectroscopy with selective detection of fluorescence. For each band of the individual isotopomers, about 130 line positions with a measurement accuracy of approximately 0.003 cm-1 were employed in a least-squares fit of the excited state molecular parameters. The principal results for the A2Pi state are Ae = 302.432(1) cm-1 and Re = 2.7147(1) Å. Copyright 1998 Academic Press.
