The relation between the variation-perturbation method and sum rule methods is explored. Thevariation-perturbation method is a simple method which yields accurate numerical results for all higher-order multipole dispersion coefficients. T&is method is related to a method which obtains bounds on dis

Investigations into the stability of the closed-shell RHF solutions for cyclic polyenes of varying ring size have been carried out in the framework of the spin-UHF and spin-PHF methods employing the PPP approximation. With increasing ring size the lowest eigenvalues from the non-singlet stability pr
