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。 Molecular oxygen can act as an electron acceptor to contact charge-transfer complexes (CCTs) with many organic compounds, creating a new CCT spectrum with the largest absorption at long wavelengths. In this paper, the comparative method was used to determine the CCT spectra of more than thirty kinds of organic compounds such as ethers, alcohols, amines and hydrocarbons. The empirical formula for calculating the ionization potentials of organic compounds from the CCT spectra was deduced, and the ionization potentials of the above thirty organic compounds were calculated.
