✦ Synopsis

The laser-induced fluorescence (LIF) spectrum of the B 3 ⌸ 0 ϩ u -X 1 ⌺ g ϩ system of Br 2 was recorded by Fourier transform spectroscopy (FTS). The LIF spectra were obtained by using continuous-wave dye laser excitation in the spectral region 16 800 -18 000 cm Ϫ1 . About 1800 rotationally resolved lines were recorded in 96 fluorescence progressions, originating from the 10 Յ vЈ Յ 22 vibrational levels of the B 3 ⌸ 0 ϩ u state and involving the 2 Յ vЉ Յ 29 levels of the X 1 ⌺ g ϩ ground state of the three isotopomers of bromine, 79

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

The extension of high-resolution observation of the electronic emission spectrum of 14 N 2 toward the infrared domain is presented. To date, rotational analysis of the widely investigated spectrum of the N 2 molecule was done in a spectral domain ranging from 2500 cm Ϫ1 to the UV. We have recorded f
