Floating Spherical Gaussian Orbital Model of Molecular Structure. II. One‐ and Two‐Electron‐Pair Systems

The floating spherical Gaussian orbital (FSGO) model is applied to the He and Be atom isoelectronic sequences and to the molecules and ions: H2, He2+ +, HeH+, H3+, H4+ +, HeH−, LiH, and BeH+. Bond lengths are predicted generally to within 5% of accurate values. The He–He repulsive interaction is also calculated.
