Magnetic tensors, nitroxide labels

Structural Studies Based on -Factor Measurements. - Accurate measurements of spin-label magnetic parameters provide important data about the structure of nitroxide radicals. These data are also required for the analysis of the molecular dynamics of spin probes. The high resolution of HF EPR makes possible accurate determination of the principal axis components of the -matrix and y4-tensor from powder pattern spectra eliminating the need to prepare and study single crystals.
