C. Stroh et al., STRONG INTRAMOLECULAR EXCHANGE INTERACTIONS BETWEEN NITRONYL NITROXIDE RADICALS BRIDGED BY OLEFINIC SPACERS, Chemical communications, (21), 1998, pp. 2337-2338
Nitronyl nitroxide radicals bridged by olefinic spacers display strong
intramolecular and antiferromagnetic exchange interactions, the magni
tude of which depends on the length of the spacer and on steric crowdi
ng around the radicaloid subunits.
