This book provides detailed information on the history, analysis and applications of chlorine and bromine isotope geochemistry. Chlorine and bromine are geochemically unique as they prefer to exist as single charged negative ions. For this reason isotope fractionation reflects mostly processes that are not related to changes in the redox state and this fractionation is generally modest. The book will describe the processes that are most easily detected using these isotopes Bromine isotope ratio analysis. Bromine isotope analysis of the brominated phenols was based on the earlier proposed GC-MC-ICPMS method .

Mass numbers of typical isotopes of Bromine are 79; 81. Atomic Mass of Bromine. Atomic mass of Bromine is 79.904 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element Bromine has many physical properties. It has a red-brown color. It is a dense liquid with a melting point of -7 ° Celsius and a boiling point of 58.9 ° Celsius. It is nonmetallic and heavy. Bromine evaporates easily at room temperature because it is a liquid. It has an unpleasant odor and is three times as dense as water Chlorine, bromine, and sulfur can all be identified by their isotopic ratios. The isotopic ratios of commonly encountered elements are summarized in Table 6.1. In Table 6.2, the ratios have been normalized to the most abundant isotope to illustrate the expected peak ratios in a mass spectrum Here's what I got. Well, you got the abundance of bromine-79 right, but that's about it. When you set up the equation to find the atomic mass of bromine-79, i.e. x, you added the abundance of bromine-81 with the atomic mass of bromine-81 instead of multiplying these two values. So instead of color(red)(cancel(color(black)(79.904 = 0.5069 * x + 0.4931 + 80.9163) you should have had 79.904 = 0.
