摘要：

The dipole relaxation mechanism of carboxylic esters has been studied through the dielectric measurements of seventeen aliphatic esters in cyclohexane solution at 25 °C. The dielectric relaxation times obtained in this experiment are compared with those obtained for a number of rigid molecules under the same conditions. This result indicates that the dipole relaxation process of these esters RG∗OOR′ is dominated by intramolecular rotation around the G-G bonds and/or the O-G bond rather than that around the C∗-O bond. © 1980 The Chemical Society of Japan.
