, 文献中提到对频率分析用一个校正因子,例如"...B3LYP/cc-pVTZ level were scaled by an average factor of 0.975 to compensate for uncertainties arising from vibrational anharmonicity...",是在freq算完之后直接手动把频率乘0.975吗,高斯说明书里有专门的加频率换算因子的关键词,这二者是等效的吗?另外,理论级别由B3LYP/cc-pVTZ升高到MP2或CISD/cc-pVTZ并不会消除anharmonicity误差吧?谢谢~
还想请问一下谁那里有Application of the pople-santry-segal CNDO method to the cyclopropylcarbinyl and cyclobutyl cation and to bicyclobutane这篇文献吗?是有关Wiberg bond index(Wbi)的,不知道哪里可以查询Wbi值的范围对应化学键的类型。
