高斯的CBS-QB3计算输出文件中最后几项:标红线位置E(Thermal)是内能的修正,在频率计算部分内能修正的...
CBS-QB3(0K)已经包含了ZPE,E(thermal)也包含ZPE,加起来显然不是T下的内能 0.019855-0.016991-39...
The GAUSSIAN 2, GAUSSIAN 3, complete basis set-QB3, and complete basis set-APNO methods have been used to calculate DeltaHdegrees and DeltaGdegrees values for ionic clusters of hydronium and hydroxide ions complexed with water. Results for the clusters H3O+(H2O)(n) and OH-(H2O)(n), ...

基组,只写了cbs-qb3 ...对 CBS-QB3自带基组,不用另写 参见http://gaussian.com/cbs/ ...
很多年以前,曾经用Gaussian03中的CBS-Q计算过分子能量,最近再用Gaussian 09执行CBS-Q计算,发现运行...
我最近使用CBS-QB3方法计算离子液体的Pka,每次都是出现2个Normal之后,到第3轮计算时就会很慢很慢,...
1.这是不是因为体系重原子太多(12个,物质原子总个数27个左右),结构比较复杂,使用CBS-QB3不可以...
一方面差异通常来说不会明显,另一方面本来也没要求必须结构严格一致。用B3LYP/def2-TZVP优化的目的仅仅是...
