Fermi Resonance In some compounds, a normally quite weak overtone or combination band may have almost the same frequency as another fundamental vibration. As a result, Fermi resonance may occur, that is, two relatively strong bands may be observed instead of the expected one band. The vibrations involved should be in the same part of the molecule so that they can be coupled. This effect can be found in at least some cryodeposition spectra of sarin and VX homologues.
