Abstract
Bromine atoms were produced in the pulse radiolysis of neat dibromomethane (DBM) and bromoform and of cyclohexane solutions containing DBM, bromoform, carbon tetrabromide, or ethyl bromide. The Br atoms form complexes with dimethyl sulfoxide ({lambda}{sub max} 425 nm), with aromatic compounds, and with oxygen-containing compounds. In the absence of other complexing agents, since Br atoms do not abstract H from the solvents rapidly, they form complexes with their parent bromo compounds. The absorption maxima of these complexes are at 365 nm for C{sub 2}H{sub 5}Br{center dot}Br, 390 nm for CH{sub 2}Br{sub 2}{center dot}Br, 425 nm for CHBr{sub 3}{center dot}Br, and 480 nm for CBr{sub 4}{center dot}Br.
