A high-resolution resonance fluorescence spectrum of bromine excited by an electrical discharge in the region 1500-2100 Å was photographed on a 10.7-m concave grating vacuum spectrograph. Twelve resonance doublet series excited by four bromine atomic resonance lines were identified and analyzed. All doublet series have the ground state of 79,81Br2 as the lower electronic state. The vibrational numbers of these doublets corresponding to this state vary from 0 to 76. Rotational constants are obtained by least-squares fitting of the doublet separations, and the vibrational constants by least-squares analysis of vibrational term values. Probable assignments for the upper electronic state(s) of the transitions involved were suggested.
