IR Spectra of Alkanes The characteristic structural features of alkanes are the carbon–carbon and carbon–hydrogen single bonds. The stretching of the carbon–carbon single bond is infrared-inactive (or nearly so) because this vibration is associated with little or no change of the dipole moment. The stretching absorptions of alkyl CLH bonds are typically observed in the 2850–2960 cm

Infrared Spectroscopy (IR) What IR does IR detects frequencies of infrared light that are absorbed by a molecule. Molecules absorb these frequencies of light because they correspond to frequencies of vibrations of bonds in the molecule.
