顺便还有个小问题请教下
[a] The electronic energy calculated by B3LYP in gas phase. [b] The electronic energy calculated by N12 in chloroform solvent.
像以上注释中 electronic energy 的能量是指单点能吗?自己重复了下并不能符合文献数值,高斯版本是相同
下面一段是文章中对计算部分的描述,是我的理解错误了吗?请教各位 谢谢
All the density functional theory (DFT) calculations were carried out with the GAUSSIAN 09 series of programs.
DFT method B3-LYP3,4 with a standard 6-31G(d) basis set (SDD basis set for Ru) was used for geometry optimizations.
Harmonic frequency calculations were performed for all stationary points to confirm them as a local minima or transition
structures and to derive the thermochemical corrections for the enthalpies and free energies. The minimum energy
crossing point (MECP) in this work were located with the code developed by Harvey and co-workers at a B3-LYP/6-
31G(d) level.5-7 N12 functional,8 which could give more accurate energetic information, is used to calculate single point
energies. Solvent effects were considered by single point calculations on the gas-phase stationary points with a SMD
continuum solvation model.9-11 The larger basis set 6-311+G(d, p) (SDD for Ru) is used in the solvation single point
calculations. The energies given in this work are the N12 calculated Gibbs free energies in chloroform solvent. |
