Question
Transcribed Image Text:3. Bromine, Br2
Consider the fragmentation of diatomic compounds. For example, 158Br2 will give a
signal at 79 for 79Br and one at 79 for Br. Br has two naturally occurring isotopes, the
79 isotope and the 81 isotope. Determine the origin (formula) of each of the signals for
the mass spectrum of molecular bromine. Example, 158Br2 is equal to 79Br79Br.
