Notes:
A simple optimization method for orbital exponents embedded in a molecular wave function is proposed by combining the uniform scaling technique and the energy gradient method with respect to nuclear positions. No additional gradient calculations are needed. In this method, all the exponents are optimized through a single common scale factor and the resulting wave function satisfies the virial theorem. Illustrative examples are given for several simple molecules.
