An efficient algorithm for parallelization of a molecular mechanics program operating in the space of internal coordinates such as dihedral angles, bond angles, and bond lengths is described. The iterative procedure to calculate analytical energy derivatives with respect to the internal coordinates
## Abstract By using twoβ and threeβbody internal coordinates and their derivatives as intermediates, it is possible to enormously simplify formulas for threeβ and fourβbody internal coordinates and their derivatives. Using this approach, simple formulas are presented for stretch (twoβbody), two ty
Simple and very efficient formulas are presented for four-body ## Ε½ . out-of-plane bend used in MM2 and MM3 force fields and improper torsion Ε½ . used in the MM4 force field internal coordinates and their first and second derivatives. The use of a small set of bend and stretch intermediates allow
