摘要：

The C≡N stretching frequency, νC≡N, is affected by change in the solvent and also by change in concentration in the same solvent. In the case of acetonitrile, νC≡N is in Fermi resonance with the combination tone (δsym. CH3 + νC-C), and the degree of Fermi resonance interaction changes with change in the solvent. With the exception of dimethyl sulfoxide, unperturbed νC≡N for acetonitrile exhibits a pseudo-linear correlation with the acceptor number of the solvent.
