Using the optimized effective potential method in conjunction with the semianalytical approximation due to Krieger, Li, and Iafrate, we performed fully selfconsistent exact exchange-only density functional calculations for diatomic molecules with a fully numerical basis-set-free molecular code. The

β¦ Synopsis
The MNDO Hamiltonian as incorporated within MOPAC has been utilized to predict dynamics for some simple reactions. In one option, the intrinsic reaction coordinate has been followed along the path of steepest descent from the transition state backward to reactants and forward to products. In a second option, dynamics of isolated molecular systems have been calculated. In each case, the potential surface (as predicted by the MNDO Hamiltonian) is calculated in situ as the atomic trajectories are calculated from Newton's Laws of Motion. Several specific examples are given and discussed.

## Abstract This article describes a number of algorithms that are designed to improve both the efficiency and accuracy of finite difference solutions to the PoissonβBoltzmann equation (the FDPB method) and to extend its range of application. The algorithms are incorporated in the DelPhi program. T
