Electron spin resonance evidence for dimer formation in high spin iron(III)-octaethylporphyrin and iron(III)-meso-nitro-octaethylporphyrin in solution
Abstract
E.s.r. signals representing a dimeric species and another form of aggregation in high-spin FeIIICl-meso-nitro-octaethylporphyrin (OEP)(1) are presented, and a spectral assignment is made for the dimer signal to a transition within the lowest triplet levels.
