摘要：

Coumarin exhibits two infrared bands in the carbonyl stretching region of the spectrum. The doublet is due to Fermi resonance (F.R.) of the carbonyl stretching mode, vC=O, with an overtone of a lower-lying fundamental. The vC=O mode was corrected for F.R. in a series of solvents and solvent systems, and unperturbed vC=O was correlated with mole % solvent A/solvent B, and other parameters. The cause of shifts of vC=O in solvent systems is the result of several parameters, including bulk dielectric effects, basicity of the carbonyl group, and steric factors of both the solute and solvent.
