Abstract
Calculations with pseudopotentials of double‐zeta quality have been performed on ethylene, acetylene, and water molecules. A description of the carbon–carbon double and triple bonds is presented in the framework of the pseudo‐FSGO method. A possible model of the oxygen lone pairs has been established and its functioning has been proved by calculations on the water molecule.

## Abstract New psudopotentials of higher quality have been used in __ab initio__ molecular calculations. Simple molecular systems like Li~2~, LiH, and BeH~2~ have been investigated with varying basis sets. Energy, geometrical parameters, and dipole moments have been determined. The convergence pro
## Abstract An __ab initio__ LCAO SCF MO calculation was performed on planar Fe‐porphine with a double zeta basis set consisting of 300 CGTO's. SCF wave functions of several states of Fe‐porphine and its cation were obtained. The net charge of Fe is in the range of 1.39 to 1.53. The highest occupie
