## I A particular formulation of the distributed Gaussian basis-set approach, the extended Gaussian cell model, is applied to the simplest polycentric molecule, the linear H:+ ion. Calculations of the total energy using two extensions of the original Gaussian cell model are described and results a

## Abstract Contracted basis sets of double zeta (DZ) quality for the atoms from K to Kr are presented. They were determined from fully optimized basis sets of primitive Gaussianβtype functions generated in atomic HartreeβFock calculations. Sets of Gaussian polarization functions optimized at the M
## Abstract Gradient optimized constrained (2__s__ β 2__p__) and unconstrained (2__s__ β 2__p__) Gaussian 3G basis sets are reported for the firstβrow atoms and ions __X__^__O__^, for __Q__ = β2 to +4. Analytic equations have been fitted to the logarithm of the exponents as a function of the nuclea
## Abstract A method is given for obtaining the common molecular integrals over generalized gaussian functions: The present algorithms are expected to be more efficient than those given in earlier work by the same author.
