Correlation consistent basis set
WebA basis set in chemistry is a set of functions used to create the molecular orbitals, which are expanded as a linear combination of such functions with the weights or coefficients to be determined. Usually these functions are atomic orbitals, in that they are centered on atoms, but functions centered in bonds or lone pairs have been used as have pairs of functions … WebApr 13, 2024 · Full correlation matrix calculation.

Unprecedentedly, it can be reliably extrapolated to the complete basis set limit (CBS) from as small as Pople's STO-2G up to the largest aug-cc-pVXZ basis sets of Dunning's correlation-consistent type and even …
Some of the most widely used basis sets are those developed by Dunning and coworkers, since they are designed for converging post-Hartree–Fock calculations systematically to the complete basis set limit using empirical extrapolation techniques. For first- and second-row atoms, the basis sets are cc-pVNZ where N = D,T,Q,5,6,... (D = double, T = triples, etc.). The 'cc-p', stands for 'correlation-consistent polarized' and the 'V' indicates the… WebMay 7, 2024 · For the Be atom, a hierarchy of basis sets was developed for cardinal numbers up to 6 using the ideas of the correlation- consistent GTO basis sets. For numerical stability in the basis set optimization, it was found most convenient to use STO basis with \(n = \ell + 1\) in Eq. in agreement with the choice for GTO basis sets. The …
