In this work, the basis set superposition error (BSSE) has been analyzed for the systems Cu 2 , Cu 3 , Cu 6 and Cu 13 as prototypes of metallic clusters. Various basis sets have been tested. In addition, pseudopotentials of 1- and 19-valence electrons have also been studied in ...

The effect of the basis set superposition error is investigated at both SCF adn correlated levels,using the pairwise additive function counterpoise (PAFC),the site-site function counterpoise (SSFC),and the White and Davidson method,for [Li(NH_3)_N]~(q+)(n=1-4;q=0,1)clusters.The PAFC...

Individual minima were located on the PES employing the counterpoise (CP) correction to account for the basis set superposition error (BSSE). Apart from these canonical MP2 calculations local MP2 (LMP2) calculations were performed. For the latter the BSSE at the correlated level is inherently ...

See also the Basis set superposition error (BSSE) tutorial. For other alternative elements, for instance that have a non-integer nuclear charge, one should use one of the standard chemical symbols. The BASIS key will use this chemical symbol for selecting the basis set for this alternative ...
For treating BSSE(Basis Set Superposition Error), we allow for the inclusion of “empty” or “ghost” atoms in the calculation. Namely, when expanding the Hamiltonian, basis sets on the atoms are used, while the ionic potentials on those atoms are not included when constructing the Hamiltonian...

However, we are able to demonstrate that the basis set requirements in the molecule are ameliorated by a positive kind of basis set superposition effect from the basis functions on the counterion.查看原文 中文翻译 设置离子系统中相互作用的基础要求:LiCl 我们已经检查了描述原型离子分子LiCl的特性的...
