概要
- 論文の詳細を見る
The C=O stretching frequencies in acetone, mesityl oxide, acetophenone and benzophenone were measured in various solvents and the frequency shifts induced by solvents were interpreted by McRae's theoretical equation. Results show that the observed shifts can be explained in terms of the coöperating interactions between solute and solvent molecules.<BR>Next, the intensity of the C=O group vibration bands of these ketones was observed and compared with bond moment derivatives calculated by diatomic molecular appoximation. Small changes of about 1 D/Å were observed for polar and nonpolar solvents. The increase of the bond moment derivative value in a hydrogen bonding system was attributed to the charge transfer force.
