 Title: REEXAMINATION OF THE EMISSION SPECTRUM OF $Br_{2}$ IN FOREIGN GASES Creators: Berwanger, Patrick C.; Ashmore, J. Gail; Viswanathan, K. S.; Tellinghuisen, Joel Issue Date: 1981 Publisher: Ohio State University Abstract: The UV emission spectrum of $Br_{2}$ is studied as a function of pressure, temperature, and isotopic species. Most of the electronic bands appearing in the $Br_{2}$ spectrum seem to be analogues of those occurring in the $I_{2}$ spectrum. For example the strongest system near 2900 A and a broad band near 3600 A both appear to originate from the D$^{\prime}$(2g) state. The system near 3100 A appears to be the analogue of the 4300-A (E-B) system in $I_{2}$. Our reanalysis of this system confirms the earlier $conclusion,^{1}$ that the B state is the terminus. However we obtain considerably different constants for the excited (E) state. Work continues on other electronic bands in the $Br_{2}$ emission spectrum. Description: $^{1}$ P. Venkateswarlu and R.
