Some Calculations of Nuclear Spin-Spin Couplings,ns only. Couplings for heavier nuclei require a relativistic theory for their interpretation. The importance of both non-specific and specific medium effects on spin-spin couplings is discussed. Examples are presented which illustrate the more chemically interesting aspects of the various coupling phenomena considered.
