✦ Synopsis

The combination of molecular spin densities and of structural data is shown to provide a sensitive test for the fme strut-' ture splittings and principal axes of triple; spin excitons in organic ion-radical crystals, in support of weakly-perturbed molecular sites in these solids. The exchange pathway in Rb(TCNQ) and the occurrence of dirner radicals, with fractional charges, in several tetrameric (TCNQ$ stacks illustrate the comparisons afforded by computations of fine structure parameters for tiplets states in the solid.
