Atomic Absorption Spectrometry (AAS)
cdn.intechopen.comThe instrument used for atomic absorption spectrometry can have either of two atomizers. One attachment is a flame burner, which uses acetylene and air fuels. The second attachment consists of a graphite furnace that is used for trace metal analysis. Figure 1 depicts a diagram of an atom ic absorption spectrometer. Fig. 1.
Carbon Dioxide Absorption in the Near Infrared

Bromination of Cinnamic acid
www.rsc.orgbrominated carbon atom and also the effect of the bromine in the chemical shift of the carbon atoms. In the following figures are given, as examples, the 1H and 13C NMR and IR spectra of 2,3-dibromo-1,3-diphenylpropan-1-one. Carbonyl groups are one of the most important structural units that can be revealed by IR spectroscopy.

Verapamil is converted into the norverapamil in which the nitrogen has been N-demethylated. Norverapamil is only about 20% as active as the parent active molecule.
