โœฆ Synopsis


The electron projection function P(r, z ) = S p b , y, Z) dy is used to evaluate charge transfer and covalency in two series of molecules, LiX and CH3X (X = Li, BeH, BH2, CH3, NH2, OH, and F), with wavefunctions derived from STO-3G, 4-31G, and, in some cases, 6-31* ab initio calculations. The precision of the method and comparison with Mulliken populations analysis are described. Particular attention is given to CH3Li which by our criteria is wholly ionic.

In the present work we show that one can build accurate wavefimctions depending upon few variational parameters for ground and excited states of two-electron diatomic systems. Such simple wavefunctions could be useful in collisional problems. A convenient expression to compute the energy is also giv

A simple method is introduced to decompose the electronic density of a molecule into the sum of fragments. The method is based on Hirshfeld's partitioning scheme. For flexible molecules, one can verify that the density of the fragments around a single bond is invariant to an accuracy better than 0.0
