"In chemistry, resonance is a way of describing bonding in certain molecules or ions by the combination of several contributing structures (or forms, also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory."

This is a different use of the word "resonance".

In the case of IR spectroscopy, the resonance frequency is just the frequency of IR radiation (usually quoted in the unusual units of cm-1 rather than the usual Hertz) that a particular bon absorbs at. e.g. for most C=O bonds it is about 1745 cm-1, for C-h bonds about 3000cm-1 etc etc
