咨询一下老师:我是用选定泛函的方式计算了分子,然后审稿有这段话说的是什么意思,我对理论不太理解:Such non-empirically-optimized functionals are often obtained by tuning parameters such that the Koopmans' theorem is satisfied. The authors should describe how well Koopmans' theorem is satisfied with their optimized method. 谢谢老师。
这个审稿人问的这个 tuning parameters such that the Koopmans' theorem is satisfied.是不是就是当时在论坛里讨论的LC-wpbe这样的泛函,调节w的这个意思?
A:
否,你看LC-wpbe原文和相关的测试,根本没有koopman的事
专门去调参数去尽量满足koopman定理的泛函也很少有这么做的
Q:
满足Koopmann定理,说的是调泛函参数使之跟电离能数据吻合么?
Ionization energies calculated from DFT orbital energies are usually poorer than those of Koopmans' theorem, with errors much larger than two electron volts possible depending on the exchange-correlation approximation employed.
