WebThe carbonyl stretching absorption is one of the strongest IR absorptions, and is very useful in structure determination as one can determine both the number of carbonyl groups … WebThe peaks show areas of the spectrum where bonds are vibrated. The IR spectrum of a molecule can be expressed as a function of wavelength. For example, in the case of water, the wavelength of light emitted from the water molecule is about 380 nanometers (nm). This wavelength corresponds to a wavelength range of about 0.1 to 1.5 micrometers (μm). WebMar 26, 2016 · Recognizing where the absorptions generated by the common functional groups occur will help you to interpret IR spectra.
