Abstract: | A linear magnetic field gradient superimposed on the main static field was used to study one-dimensional diffusion of perchlorotriphenylmethyl radicals in decalin and of oxygen molecules in polytetrafluoroethylene. A simple method is developed for deducing diffusion coefficients from both time-dependent and single-scan experiments provided that the natural linewidth is small relative to the field change over the diffusion distance. |
