A better description of the molecule in Exercise E9B.1(a) might be obtained by including more orbitals on each atom in the linear combination. Normalize to 1 the molecular orbital ψ = ψA + λψB + λ′ψB′ in terms of the parameters λ and λ′ and the appropriate overlap integrals, where ψB and ψB′ are mutually orthogonal and normalized orbitals on atom B.
