Inner projections of the polarization propagator were used to study the indirect through-space transmission of the Fermi contact tern of C-F couplings via a C-X (X = F, H) intermediate bond. When X = 33 a large capability for trans- mitting this component is observed. But for X = F a notable inhibit

✦ Synopsis
The IPPP method (inner projections of the polarization propagator) is extended to include the orbital and dipolar interactions of spin-spin coupling constants. As an example. calculations of the through-space components of F-F couplings are carried out at the INDO level of approximation in fluorinated derivatives of cis-fluoropropene.
The orbital and dipolar throyh-space couplings are much smaller than the Fermi contact term. However. the first one, thouph small, is not negli_sibIe.
