Mass Spectrometry of Bromine, Br2
- Bromine has 2 isotopes 79Br and 81Br in an approximately 1:1 ratio
- specificlly 50.5:49.5
- Thus, the bromine molecule may be composed of two 79Br atoms (mass 158 amu)
- a more probable combination of 79Br-81Br (mass 160 amu)
- two 81Br atoms (mass 162 amu)
- Fragmentation of Br2 to a bromine cation then gives rise to equal sized ion peaks at 79 and 81 amu.
