ANALYSIS OF ENERGY TERMS AFFECTING THE GEOMETRY OF THE BEH2 AND WATER-MOLECULES - A CLASSICAL INTERPRETATION - OF THE FLOATING SPHERICAL GAUSSIAN ORBITAL MODEL OF MOLECULAR-STRUCTURES

The energy terms arising in the calculations of BeH2 and H20 mole­cules by the FSGO method are analysed as a function of the bond angle in order to gain insight into the reasons for the particular equilibrium con­figurations. The analysis is made in terms of symmetrically orthogonalized orbitals so as to exclude three and four-orbital electron repulsion terms.
