✦ Synopsis
The energy band structure of an infinite hydrogen cyanide chain is calculated within the Hartree-Fock scheme for solids in the linear combination of atomic orbitals form using the STO-3G basis set. The hydrogen bond stabilization energy is 9.76 kcaI/moI for the most stable proton position considered. The charge distribution differs strongly from that of smaI1 clusters.
Consider@
infiiite hydrogen bonded systems we wish (also see ref.
[I] ) to get insight into the "coIlective nature" of the hydrogen bond. Apparently the ab initio Hartree-Fock (HF) crystal orbital (CO) method

## 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
