WebInfrared Spectroscopy: Fingerprint region . The fingerprint region is the area of the spectrum that is below 1500 cm-1. This region contains absorptions for some complicated vibrations which are usually caused by the bending or stretching of single bonds. Due to this, the pattern in this region is very complicated and is unique to the molecule. WebThe IR spectrum is created by recording the frequencies at which a polar bond's vibration frequency is equal to the infrared light's frequency. The fingerprint region is separate from the function group region, and generally corresponds to …
