WebBromine isotope geochemistry is in its beginning stages. Bromine has two stable isotopes, 79 Br and 81 Br, having relative mass abundances of 50.686% and 49.314%, respectively ( Eggenkamp and Coleman, 2000 ). Variations in isotopic composition are reported as δ 81 Br (SMOB), where SMOB is standard mean oceanic bromide. WebThe Origin of Fragmentation Patterns When the vaporized organic sample passes into the ionization chamber of a mass spectrometer, it is bombarded by a stream of electrons. These electrons have a high enough energy to knock an electron off an organic molecule to …
