✦ Synopsis
The spectroscopy of the Br 2 B 3 P(0 / u ) -X 1 S / g system has been revisited using both high-resolution Fourier transform spectroscopy and laser-induced fluorescence techniques. Improved rotational constants are reported based on an analysis of 97 vibrational bands observed in absorption at 0.02 cm 01 resolution for the 79 Br 79 Br isotope, including £ Å 6-39, £Љ Å 0-5, and JЉ £ 84. In addition, over 100 bandheads in the 79 Br 81 Br isotope were identified from laser-induced fluorescence transitions originating from 15 £ £ £ 21 and terminating on high-lying vibrational levels in the ground electronic state, 1 £ £Љ £ 27. The vibrational constants for the X 1 S / g state extended to £Љ Å 27 are v e Å 323.88 cm 01 , v e x e Å 1.0696 cm 01 , and v e y e Å 00.00280 cm 01 .
