WebJan 26, 2013 · If a stretch does not change the dipole moment, there won't be any IR band. This is why O 2 and N 2 in the atmosphere don't show any IR bands. CO 2, however, has a stretch where one O moves in and the other moves out: Thus we see this band at 2300 cm-1. Back to CH362 Home Page. Web11 Fingerprint region • 1500 cm-1 or less is fingerprint region - unique to a molecule • But dull C–C, C–N & C–O roughly same reduced mass and bond strength - so nothing distinctive • Deformations (or bending) occurs at low energy as well • Very few are useful Summary of absorptions in IR spectra Position of band reduced mass light atoms - high
