【 摘 要 】

The carbonyl stretching vibration, ロC=O of 2-cyclohexene-1-one, is in Fermi resonance with a combination tone. The amount of Fermi resonance interaction between these two modes is dependent upon the amount of solute/solvent interaction due to hydrogen bonding between the carbonyl oxygen and the solvent proton. The corrected ロC=O frequency of 2-cyclohexene-1-one occurs at a lower frequency than the observed ロC=O mode of cyclohexanone, possibly caused by expanded conjugation effects. The carbonyl stretching modes of cyclic ketones were also affected by interaction with the ROH/CCl₄ mixed solvent system.
