This investigation is a continuation of a study on the optimality of MO basis sets of Gaussian functions, when constructed from AO basis sets optimized for the neutral atom or for ions. A formal charge parameter Q is used to adjust AO basis sets to the molecular environment, by virtue of a simple quadratic equation. Calculations are performed on a series of seven C2 hydrocarbons (C2H2, C2H4, C2H6, C2H3 + (open), C2H3 + (bridged), C2H5 + (bridged), and C2H4 radical anion). A simple rule is formulated to give approximate values of the charge parameter Q.
