A computer program was used to determine the principal values of g and D, the spin–spin interaction tensor, for the impurity triplet, to locate them within the host lattice and, by inference, to place them on the C2h structure of the trans dication guest. Within experimental error, g and D are coaxial, not a requirement of the dication symmetry. The minimum principal value of g (2.0022) and the intermediate value of D (218 MHz) both lie within less than 2° of the perpendicular to the molecular plane, as expected for a π radical and as required by symmetry. Within the dication plane, the maximum principal values of g (2.0271) and of D (−395 MHz) lie 15° from the CC bond. Classical calculations of the dipolar coupling support these observations and their interpretation in terms of a biradical character of the triplet state in which the unpaired electrons are effectively isolated, one in each ring.
