title: The origin of an EPR signal observed in dithiocarbamate-loaded tissues. Copper(II)-dithiocarbamate complexes account for the narrow hyperfine lines.
abstract: We examined the electron paramagnetic resonance spectra of some copper(II)-dithiocarbamate complexes in various media at liquid nitrogen temperature. It is demonstrated that Cu(II)-dithiocarbamate complexes exhibit atypical spectra with narrow hyperfine splitting, and that the dithocarbamates forming a water-insoluble Cu(II) complex are permeable in tissues, while those yielding water-soluble complexes are not.
