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

โฆ 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.

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
