Symmclry-adapted pcrlurbntion theories published so far are criticised. I<stra conditions imposed in most of these formalisms arc found to be not al.,~ays physically adcquatz. N'e conclude that the form&m proposed by Hirschfclder 2nd Silbey is ihc mosl appropriate.
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
