Formulas are given for convergence-accelerated lattice sums over all intermolecular Coulomb, London, and repulsive interactions. Their implementation in the consistent force field is described. Optimum values of convergence constant and summation limit are found for r-12, r-', and r-l interaction te

β¦ Synopsis
An algorithm has been developped for the computer generation of the possible conformations of non-planar cyclic molecules. This algorithm has been used successfully to select the known conformations of the ribose ring, of substituted cyclohexane and of disulfide bridged peptides. Its use may be extended to open molecules when the end-to-end distance is known or imposed.

## Abstract The program Generate, aimed at generating 3βD structures for peptides and peptidomimetics, is presented. The algorithm is based on a buildβup procedure, using a library of conformations of amino acid residues. This library is built from conformational analysis of amino acids placed in a
A simple method for incorporating bond-length constraints in Monte Carlo simulations of cyclic and linear molecules is described. As an example, the conformational behavior of five even-numbered cyclic alkanes is studied using Monte Carlo simulation and the MM2 force field.
