Semilocal density functional theory predictions for the barrier heights of representative hydrogen transfer, heavy-atom transfer, and nucleophilic substitution reactions are significantly improved in non-self-consistent calculations using Hartree-Fock orbitals. Orbitals from hybrid calculations yield related improvements. These results provide insight into compensating for one-electron self-interaction error in semilocal density functional theory.
在使用哈特里-福克轨道的非自洽计算中，半局域密度泛函理论对代表性氢转移、重原子转移和亲核取代反应势垒高度的预测有显著改善。混合计算得到的轨道也有相关改进。这些结果为补偿半局域密度泛函理论中的单电子自相互作用误差提供了见解。
