Abstract: The application of pulsed field gradient NMR to the measurement of diffusion in solid samples met several difficulties. A strong magnetic field oscillation at the sample probe was observed in an electromagnetic NMR spectrometer with an external lock umt. A pulse sequence is proposed to be useful in the diffesion measurement in polymer gel samples.
