Two simple approaches of the method of 'atoms in molecules' developed by Moffitt and Hurley have been applied to the lowest 1Σ u+ state of the hydrogen molecule. A trial wave function made up from a linear combination of a covalent (1s 2pσ) and an ionic structure (1s2) was used. The effect of different procedures used for selecting orbital exponents and mixing coefficients of covalent and ionic functions was studied and, in particular, the risk of using a minimization procedure was considered.
