Abstract: The infrared spectra of p-benzoquinone were measured in 13 solvents. The rule of Fermi resonance was validated by Bertvan changing solvent method. The Fermi resonance mechanism studied by changing solvent method was explained by means of KBM equation and electron donor-receptor model. The relationship between Fermi resonance intensity ratio (R) and the solvent dielectric constant (ε) was given.

Key words: Fermi resonance, solvent effect, dielectric constant, infrared spectrum
