A formulation of double perturbation theory is described which allows symmetry to be included in those cases where the z,ereorder hamiltonian does not contiin the full symmetry of the problem. As an example-we apply the fl~cov to the Epstein-Johnson spin model. 1 .-Introduction 2. Theory Some years

## Abstract Consideration is given to the problem of interactions between molecular systems (magnetic couplings being neglected) by highlighting the fact that the main difficulty of a perturbation theory that takes into account the exchange effects, resides in the differentiated symmetry of the unp
