## Abstract Several useful “redefined zero‐order Hamiltonian” variants of the Rayleigh–Schrödinger perturbation theory are derived by exploiting the freedom of choice for the orthogonality integral between zero‐ and first‐order wavefunctions. It is found that the more common Hamiltonian repartition
