Abstract
A molecular LCAO Hartree‐Fock procedure was used to calculate total energies of axially stretched normal paraffins containing up to nine carbon atoms. The results are used to model the mechanical properties of polyethylene.

## Abstract The molecular geometry of 1‐fluorosilatrane was optimized fully by restricted Hartree–Fock (HF) calculations using the 3‐21G, 3‐21G(__d__) and 6‐31G(__d__) basis sets, with the aim of locating the positions of the local minima on the energy hypersurface. The optimized geometries were co
