WebAn infrared spectrum, obtained by passing infrared radiation through a sample of a compound, is a plot of the percent transmission of radiation versus the wavenumber (or wavelength) of the radiation transmitted ( Figure 14.13 ). The instrument used to obtain an infrared spectrum is called an IR spectrophotometer. WebThe infrared spectrum reveals vibrations of atoms in molecules. The beauty of the spectrum is the close and accessible relationship between infrared bands and molecular structure. Certain groups of atoms have characteristic vibration frequencies which persist in different compounds. These groups (i.e. Si-OCH 3, C=O, Si-CH=CH 2, BF 4 rdf standardization body https://urbanhiphotels.com
