AuX(X=O,S)低电子态的理论研究OA北大核心CSCDCSTPCD
Theoretical Studies on Low-Lying States of AuX (X=O, S)
通常要用多参考态方法才能合理处理需考虑旋轨耦合(SOC)效应的开壳层分子如AuO和AuS的低电子态.事实上,通过选取合适的参考态,采用运动方程耦合簇方法(EOM-CC)也能计算这些分子的一些低电子态,而且EOM-CC方法是单参考态方法,使用起来比多参考态方法更加简单.本文采用最近发展的含旋轨耦合的EOM-CC计算电离能的方法(EOMIP-CC),选取对应的负离子为参考态,在CCSD级别上计算了AuO和AuS低电子态的性质.在不考虑旋轨耦合时,通过…查看全部>>
Multireference approaches have commonly been employed to calculate low-lying states of open-shel molecules with spin-orbit coupling (SOC), such as for AuO and AuS. However, by choosing a proper reference state, the equation-of-motion coupled-cluster approach (EOM-CC) can also be used to calculate some low-lying states of these molecules. Furthermore, the EOM-CC approach is a single-reference method and, therefore, more easily employed than multireference app…查看全部>>
