When all LF parameters are evaluated, they can be introduced into a favoured LF program [37-39] to yield all multiple energies and expectation values of all operators for comparison with experiment. In the case of d Fe04 with tetrahedral symmetry, energy matrices can be written explicitly (Table 19-2) the role of single excitation (for the T2 and Tj terms) and double excitations (for Aj, E, T2 and Tj) is important - we return to this point when we look at applications later in the article. According to this procedure, both dynamical correlation (via the DFT... 

In a molecular dynamics simulation, it takes a double loop to calculate the potential energy or force, and the time for this calculation is proportional to N, which is the most time-consuming and computationally expensive part in the simulation and limits the speed of the program execution. For short-range interactimis, since the potential value drops to zero very rapidly as the distance increases, it is a commcm practice to restrict the evaluation of the interaction potential to a limited region of space. A cutoff radius, R, is usually introduced, beyond which the interaction potential is set as zero. A conunon choice is... 

The electronic wavepackets are determined in an expansion with the configuration state functions (CSF) of single and double excitations (CISD) with the STO-6G basis set. This basis set is obviously small, but the main concern in this work is not the accm-acy but qualitative insights about the dynamical electrons in the course of chemical reactions. The program codes for the semiclassical Ehrenfest theory (SET) have been implemented in the GAMESS package [357]. 

The scalar types float or double of CH--f don t take care of special information which would be necessary to optimize a multibody dynamics formalism programmed in matrix and vector notation. Even a standard optimizer isn t capable to do this to a full extent. Important optimization information of scalars are...
