| 摘 要： | 以各种醇为溶剂测定了丙酮和环己酮的羰基紫外吸收能量ΔE,讨论了ΔE与醇分子结构的关系。结果表明ΔE与醇分子中烷基的极化效应指数PEI有良好的线性关系:ΔE=a+bPEI。

| Abstract: | Using a series of alcohols as solvents, the ultraviolet absorption energy (ΔE) values of carbonyl (C=O) for acetone and cyclohexanone were determined. The relations between those ΔE values and the molecular structure of solvent alcohols were discussed. The obtained results showed that there is a good linear relation between the ΔE value and the alkyl polarizability effect index PEI value of alcohol molecule, that is ΔE=a+bPEI. |
