| 摘 要： | 分子氧可以作为电子受体与很多有机化合物形成接触电荷转移复合物(CCT),从而在长波处产生新的具有最大吸收峰的CCT光谱。 本文采用比较法测定了醚类、醇类,胺类、烃类等三十多种有机化合物的CCT光谱。推导了从CCT光谱计算有机化合物电离势的经验公式,并由此计算了上述三十多种有机化合物的电离势。

| Abstract: | Molecular oxygen, as an electron acceptor, can interact with many organic compounds to form contact charge transfer complexes (CCT) which have the maxima absorption at longer wavelengths than that of the original components. In this paper, the UV-Vis spectra of more than 30 CCT formed from oxygen with organic compounds, including ethers, alcohols, amines as well as hydrocarbons, were measured by the comparison method. An empirical equation related to the ionization potentials of the organic compounds and the wavelengths of the maxima absorption of CCT was proposed. |
