The determination of minima and saddle points on the potential energy surfaces of the hydrogen bonded species 02-HF and 0,-H20 is performed with unrestricted Hartree-Fock calculations. Geometries, electron density distributions, and relative energies for every stationary point are reported. Only one

β¦ Synopsis
In this article, a modification of a procedure proposed by Zirrilli et al. for solving nonlinear equations is presented. The method permits the computation of minima and saddle points of energy functionals. The Muller-Brown test potential and the quantum chemical description of some proton transfer reactions are given as examples.

Optimum geometries are computed at both the SCF level of theory and the level of second-order perturbation theory for several isomers on the potential energy hypersurfaces of GeCH , GeSiH , and Ge H , including linear structures, methylene-2 2 2 2 carbenelike structures, dibridged structures, and mo
## Abstract The topological resonance energy (TRE) model was introduced independently by the Zagreb Group (in 1975) and by Aihara (in 1976). Several practical obstacles arise in the computation of TRE. Ways to surmount them are pointed out. Descriptions of algorithms, optimizations, and the efficie
The multidimensional potential energy surface for a soluble analog of a chiral phase is computed with MM2 and MNDO. Minimum energy conformations are located. The minimum energy reaction pathway between these forms is located, and the templating ability of these phases is described.
