Observation and deconvolution of a unique EPR signal from two cocrystallized spin triangles
A 16-line pattern has been theoretically predicted, but hitherto not reported, for the Electron Paramagnetic Resonance (EPR) spectrum of antiferromagnetically coupled Cu II triangles experiencing isotropic exchange of isosceles magnetic symmetry. Now, the crystallization of such a triangular species...
