Optimized Gaussian Basis SCF Wavefunctions for First-Row Atoms

Abstract
Optimum atomic Gaussian‐type‐function bases for self‐consistent‐field calculations are reported for B, C, N, O, and F, with from two to eight s functions and from one to four p functions. Orbital energies and coefficients are presented for the (3s1p), (5s2p) , and (7s3p) bases for each atom, and the functions are shown to yield lower atomic energies than previously proposed Gaussian bases of the same size.
