Abstract
When two vibrational levels of a molecule are in Fermi resonance there is a ``sharing'' of band intensity in transitions to these levels. It is shown that in exceptional cases Fermi resonance can result in an overtone or combination band being stronger than the fundamental with which it is in resonance. The theory is applied to the electronic spectrum of the NCO radical, in which such an anomaly exists.Keywords
