The nature of “A,B,C”-type infrared spectra of strongly hydrogen-bonded systems; pseudo-maxima in vibrational spectra
Abstract
The multiple maxima in “A,B,C”-type i.r. spectra of hydrogen-bonded systems are caused by Fermi resonance of νOH(broad band) with 2δOH and 2γOH such that the minima correspond to the overtone frequencies.
