用电子传播子方法计算了胸腺嘧啶和其他C-和N-甲基化尿嘧啶的光电子能谱。采用部分三阶电子传播子方法。得到了与现有实验光谱很好的一致性。讨论了电离能降低与相应Dyson轨道上甲基的反键贡献之间的关系。
Electron propagator methods are applied to the calculation of photoelectron spectra of thymine and other C-and N-methylated uracils. The Partial Third-Order electron propagator method is used. Excellent agreement with existing experimental spectra is achieved. Relationships between reductions in ionization energies and antibonding contributions from methyl groups in corresponding Dyson orbitals are discussed.
