## Abstract Optimized contracted Gaussian basis sets of doubleβzeta valence polarized (DZVP) quality for firstβrow transition metals are presented. The DZVP functions were optimized using the PWP86 generalized gradient approximation (GGA) functional and the B3LYP hybrid functional. For a careful an

β¦ Synopsis
this molecule the static difference density is known in "near HF" quality [']. As shown by comparison of the corresponding dynamic difference densities in the bonds with the corresponding "4-31 G"values['] (Table ) the mutual deviation between the two calculations does not exceed 0.16 (C-C) or 0.18e/A3 ( e N ) . "4-31 G ' calculations thus prove to be surprisingly reliable for calculations of difference densities.

at equilibrium; cf. Fig. I), according to the Hammond postulate the transition state in our case is more similar to the covalent compound than on collapse of the high-energy system of dissociated ions in dichloroethandB1. Dynamic NMR measurements therefore permit the study of barriers of ionization
## Novel expressions far electronic density distribution calculations have been derived. The derivation is based on the requirement that the center of charge is not removed. It is shown that tc the first approximation this requirement coincides with Mulliken analysis.
