✦ Synopsis

Abstract

Minimal compact contracted Gaussian basis sets are constructed for the atoms from Na to Ca. They give satisfactory valence shell orbital energies, although they are minimal‐type basis sets. Split‐type basis sets are also derived from the minimal Gaussian basis sets in order to enhance the flexibility of the basis sets for molecular calculations.

## Abstract Minimal contracted Gaussian basis sets are presented for Ga through Cd. Characteristically these Gaussian‐based minimal sets give far better __d__ orbital energies than those by minimal STO basis sets. These new basis sets were tested on Br~2~ for which a new benchmark calculation was a

## Abstract Two minimal contracted Gaussian‐type orbital (CGTO) sets are developed for the transition metal atoms. The expansion terms for the first set, MINI‐3, are 4, 3, 3, and 3 for __s__‐type CGTOs and others are all three. The abbreviation would be (4333/33/3) where the slash divides symmetry.

## Abstract The Gaussian‐type basis sets for molecular calculations are usually prepared by an atomic SCF program in which spherical coordinates are used. On the other hand, many molecular SCF and CI programs are written by using the Cartesian coordinates and as a result six‐membered __d__‐type fun

The new contracted Gaussian-type orbitals (CGTOS) for molecular calculations have been developed from Li to Ne. The CGTOs are minimal type, i.e. composed of two s-type CGTOs, sl, sz, and one p-type CGTO, pl. They are new family of cGTOS given by Tatewaki and Huzinaga, and others. In the previous wor
