基态的结构已经优化好(B3LYP/6-311+G**),但是算激发态一直出现SCF不收敛,尝试过sob老师博文《解决...
The roadblock on the way to perform the quantum mechanical calculation as the "SCF or DFT" method for some molecules such as drugs, biological molecules, and so on is that these molecules are too large to study. They need a computer with a large amount of system memory and a very fast ...
The addition of Cl, NH3, CO, C6H6 to Ti8C12 has been investigated by means of ab initio RHF and DFT calculations. The metallocarbohedrene (met-car) molecule has been modelled as a structure of a tetracapped tetrahedron with Td symmetry and two distinct metal sites, found to be most ...
