摘要：

Two bands (0-0 and 1-0) of the A(2)Pi-X(2)Sigma(+) system of (SrBr)-Sr-88-Br-79 and (SrBr)-Sr-88-Br-81 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 approximate to 0.003 cm(-1) were employed in a least-squares ft of the excited stare molecular parameters. The principal results for the A(2)Pi state are A(e) = 302.432(1) cm(-1) and R-e = 2.7147(1) Angstrom. (C) 1998 Academic Press.
