Abstract
USING the flash photolysis technique of Norrish and Porter1,2 I have discovered a spectrum consisting of a series of roughly equidistant diffuse absorption bands which is attributed to the OBr radical. This spectrum was observed when mixtures of the vapours of bromo-substituted methanes and oxygen were irradiated by a flash discharge. Chloro-bromo-methane provided the most intense absorption bands, but they also appeared with the following compounds: CCl3Br, CCl2HBr, CBr2H2, CBr4; the strongest bands were also weakly visible in mixtures of oxygen and ethyl bromide.
