Vibrating bonds in functional groups absorb energy at a frequency that corresponds to the vibrational frequency of the bond. In organic chemistry, this corresponds to frequencies of 15 to 120 THz. These frequencies are expressed as wavenumbers: wavenumber = frequency speed of light = f c. The wavenumbers range …
WebMar 26, 2016 · Functional groups are the portions in an organic molecule that dictate how the molecule will react. To generate the IR spectrum, different frequencies of infrared light are passed through a sample, and the transmittance of light at each frequency is measured. The transmittance is then plotted versus the frequency of the light (which is ... WebInfrared Spectroscopy generally refers to the analysis of the interaction of a molecule with infrared light. The IR spectroscopy concept can generally be analyzed in three ways: by measuring reflection, emission, and absorption. The major use of infrared spectroscopy is to determine the functional groups of molecules, relevant to both organic ...
