New Band Systems of the YBr Molecule
The thermal emission spectrum of the YBr molecule has been photographed in the region 4130-4750 A at a temperature about 2300degreesC using Saha's vacuum furnace at a dispersion of 3.5 A/mm on the C. Z. Ebert plane grating spectrograph. A total of 123 red-degraded bands have been recorded and assigned to two new systems, namely F-X and G-X, and one previously reported system, viz. E-X. The vibrational constants have been evaluated for these systems. Copyright 1997 Academic Press. Copyright 1997Academic Press
