79 Br: 81 Br exists naturally in an almost 1:1 ratio, so we observe peaks at 'M' (molecules with an atom of 79 Br) and 'M+2' (molecules an atom of 81 Br) are obtained with relative intensity 1:1 Note that since the relative natural abundances of the isotopes are different, you can tell the difference between the presence of Cl and Br. Bromine is an active ingredient in four products; two products with multiple active ingredients and two products as the sole active ingredient. The multiple active ingredient products control mold, mildew, fungi, insects, and odors in exposed surfaces of bedding, mattresses, textiles, drapes, upholstered furniture, rugs, carpets, and storage areas.

Notes

• Values marked # are not purely derived from experimental data, but at least partly from systematic trends. Spins with weak assignment arguments are enclosed in parentheses.
• Uncertainties are given in concise form in parentheses after the corresponding last digits. Uncertainty values denote one standard deviation, except isotopic composition and standard atomic mass from IUPAC which use expanded uncertainties.
