Abstract: | The region 3030–3140 Å of the emission spectrum of Br2 is reinvestigated using sources containing separated 79Br2 and 81Br2. The analysis, which spans v′ levels 0–15 and v″ levels 8–31, indicates that the transition in this region is the analog of the E → B system in I2, and it is so redesignated. The following spectroscopic constants are obtained for the E state of 79Br2: Te = 49 779.06 cm?1, ωe = 150.46 cm?1, ωeχe = 0.383 cm?1, Be = 0.04172 cm?1, . |
