Angular variation of linewidths in single-crystal EPR spectra.
We present the angular variation of the resonance magnetic fields as well as the angular variation of the linewidths obtained from single-crystal electron paramagnetic resonance spectra of Delta+ [Cr((-)chxn)(3lambda lambda lambda)]3+ (chxn = trans-1,2-cyclohexanediamine) doped into the nitrate salt of the isostructural Rh(III) ion Delta+ [Rh((-)chxn)(3lambda lambda lambda](NO3)3)3.H2O. An analysis of the angular variation of the resonance magnetic fields indicates axial symmetry for the cation. An analysis of the angular variation of the linewidths, on the other hand, reveals that not all the paramagnetic sites have perfect axial symmetry.
