Quantitative spectroscopy study of HBr in the 105–235 nm region.

The photoabsorption and fluorescence cross sections of HBr were measured in the 105–235 nm region using synchrotron radiation as a light source. Sharp absorption bands were observed in the 105–120 nm region. These bands were classified into Rydberg series, and their oscillator strengths were measured. Fluorescence in the ultraviolet region was observed and used to identify the V 1∑+ state. [ABSTRACT FROM AUTHOR]
