Our extension of the AM1 semiempirical molecular orbital technique, AM1*, has been parameterized for the elements Cu and Zn. The basis sets for both metals contain a set of d-orbitals. The zinc parameterization uses a filled d-shell to give 12 valence electrons. Thus, AM1* parameters are now available for H, C, N, O and F (which use the original AM1 parameters), Al, Si, P, S, Cl, Ti, Cu, Zn, Zr and Mo. The performance and typical errors of AM1* are discussed for the newly parameterized elements.
我们对AM1半经验分子轨道技术进行了扩展,得到了AM1*,并针对铜和锌元素进行了参数化。这两种金属的基组都包含一组d轨道。锌的参数化使用了填满的d壳层,以提供12个价电子。因此,现在AM1参数可用于氢、碳、氮、氧和氟(使用原始AM1参数)、铝、硅、磷、硫、氯、钛、铜、锌、锆和钼。文中讨论了新参数化元素的AM1性能及典型误差。
