WebThe IR spectroscopy in the lab does not have the ability to measure the wavelength of carbon-bromine bonds because it is not within the range of the machine. Therefore, the two IR spectroscopies of the two substances were very similar because they both contained aromatic rings with similar wave numbers (cm -1) (Table 1, Table 2). WebThe five peaks in this spectrum demonstrate clearly that natural bromine consists of a nearly 50:50 mixture of isotopes having atomic masses of 79 and 81 amu respectively. Thus, the bromine molecule may be composed of two 79 Br atoms (mass 158 amu), two 81 Br atoms (mass 162 amu) or the more probable combination of 79 Br-81 Br (mass
Webtest, the bromine test and the potassium permanganate (Baeyer) test. * Gas Chromatography (GC) is extremely useful in determining the percent composition/purity of known liquids; however, the flame ionization detector does not detect if there is water present in the product.
