Ab initio molecular orbital studies irxluding d-functions in the basis set have been made cn methane, acetylene, ethylene, ethane, propyne, allene, cyclopropene, propene and cyclopropane. It is shown that the stained cyclic molecules cyclopropene and cyclopropane are preferentially stabi!ized by the

β¦ Synopsis
A program for the calculation of one-electron molecular energy and wave function for large inter nuclear distance R is reported. Asymptotic expansion of the energy and the wave function in inverse powers of R is obtained by solving the recurrence formula.

In order to obtain wave functions, energies, and energy derivatives for molecular systems, we present a general approximation procedure based on distribution theory. We found in the testing functions space of distribution theory, an appropriate mathematical basis to overcome theoretical difficulties
The dependence of the Hiickal total n-electron energy on the molecular topology is shown. ckneid ruks governing the structural dependence of the n-electron energy in conjugated molecules are derived.
## Abstract Isostructural clusters exhibit contrasting magnetic properties when the number of electrons differs. Surprisingly, the same is true even for isoelectronic cages (e.g. __O~h~__ B~6~H~6~^2β^ is diatropic, whereas __O~h~__ Si~6~^2β^ is paratropic) or for those with different substitutents
