N2 - For pt.I see ibid., vol.4, p.761 (1971). Bounds to overlap integrals between approximate and exact wavefunctions have been derived for arbitrary excited states of quantum mechanical system, using the Lagrange multipliers technique. A new lower bound to the ground state energy which is an improvement over the classical result of Temple has also been derived.
