Abstract
THE 1π-1σ spectrum of the molecule BBr1 has been photographed in the second order of a 6.5 m. concave grating. The light source was an uncondensed discharge through BBr3vapour in a pyrex H-type tube fitted with quartz window and nickel electrodes. The rotational structure of the (0,0)-band at 2950 A. is partially resolved into lines. Measurements in the P-, Q- and R-branches, where lines up to J 90 can be observed, make a complete analysis of this band possible. The constants of the BBr-molecule are found to be:
