## Abstract A finite basis set particularly adapted for solving the Hartree–Fock equation for diatomic molecules in prolate spheroidal coordinates has been constructed. These basis functions have been devised as products of B‐splines times associated Legendre polynomials. Due to the large number of

✦ Synopsis
Distributed basis sets of s-type Gaussian function for diatomic molecules are developed in which the disposition of the off-nucleus expansion centers are determined by a stochastic variational technique. The utility of this approach is investigated by means of prototype matrix Hartree᎐Fock calculations for the ground state of the nitrogen molecule.

Accurate Gaussian basis sets (18s for Li and Be and 20s11p for the atoms from B to Ne) for the first-row atoms, generated with an improved generator coordinate Hartree-Fock method, were contracted and enriched with polarization functions. These basis sets were tested for B 2 , C 2 , BeO, CN -, LiF,
## Abstract Accurate relativistic adapted Gaussian basis sets (RAGBSs) from Cs (__Z__ = 55) through Rn (__Z__ = 86) without variational prolapse were developed by using the polynomial version of the Generator Coordinate Dirac‐Fock method. The RAGBSs presented here can be used with any of two popula
