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 …
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 5, 2024 · Introduction.
