Abstract
Stabilization energies and equilibrium distances of oneβdimensional (HF)~n~ and (H~2~O)~n~ chains have been calculated by means of the PCILO method for finite chain length and by the PCILOCC method for infinite chain length. Both types of calculation are compared with corresponding CNDO/2βMO and CNDO/2βCO calculations. Further we have performed an analysis of the individual contributions of the stabilization energies per monomer of the PCILO and PCILOCC calculations.
The results show that the PCILOCC method is well suited for the calculation of molecular associations with translational symmetry.

## Abstract The PCILO method was used to calculate the intermolecular interaction of Londonβvan der Waals type, hydrogen bonding type, and charge transfer type interactions, respectively. The stabilization energies of the calculated supermolecules are: 0.85 kcal Β· mole^β1^ for the nonane dimer, 4
## Abstract A method within the PCILO framework for the study of periodic molecular systems involving impurities is described regarding a oneβdimensional chain. The calculation of the whole system is reduced to the calculation of subsystem pairs only. By use of the firstβneighbor approximation only
