Mol Struc 311 (1994) 331-341, I. Mayer and A. Gomory describe a semiempirical method for partitioning the energy to determine the two center contibution to the total energy. We are very interested in this technique and ar interested in having this method available to us, however, the only molecular modelling software we have is Hyperchem (3.0). If it is possible for us to implement this technique as a programming extension, or if it is available via some other route, we would like to know. It is not clear to us how one would go about adding extensions to the hyperchem program. thank you for your assistance matt harbowy chemist thomas j. lipton, inc. matthew.harbowy _-at-_)tjlus.sprint.com o-cha.,at,.cnj.digex.net "I'm the bear that went over the mountain"
