✦ Synopsis

The orbital energies and the intermolecular overlap integrals of the galvinoxyl radical are calculated. It is found that the ferromagnetic intermolecular interaction in galvinoxyl can be qualitatively interpreted by a combined effect of spin polarization within the radical and charge-transfer interaction between the radicals.

An a-nitronyl nitroxide cation radical, 2-( 3-N-methylpyridinium)-4,4,5,5-tetramethyl-4,5-dihydro-lH-imidazol-l-oxyl 3-Noxide, has been found to possess a unique structure and magnetic properties: the molecules are manifested as dimers with a very short intermolecular contact between the NO group an
