WebJan 23, 2015 · Many chemists consider 1450 cm-1 to be the dividing line. Explanation: The functional group region runs from 4000 cm-1lto 1450 cm-1, and the fingerprint region from 1450 cm-1lto 500 cm-1. A typical IR spectrum looks something like the one below. The functional group region contains relatively few peaks. WebThe infrared (IR) spectral range is in the electromagnetic spectrum between the visible and microwave regions [5] and extends from 14000 cm –1 to 10 cm –1. ... In order for a vibrational mode to be active in the infrared region, the vibration must cause oscillation of the permanent dipole moment of the molecule. The alternating electrical ...
