Diffusion measurements of small molecules at the gas solid interface

University of Bristol, Bristol, England

NATO Adv. Study Inst. Ser., Ser. C (1980), 61 (Magn. Reson. Colloid Interface Sci.), 543-5


NMR diffusion measurements were made for NH3, C6H6, neopentane, and CH4 on various graphitized C blacks. Diffusion is always faster in the adsorbed state than in the resp. bulk materials. Reasonable agreement was obtained with quasielastic neutron scattering diffusion measurements.

A computer-controlled pulse sequencer for pulsed NMR experiments

T. Cosgrove, J. S. Littler and K. Stewart
School of Chemistry, University of Bristol, Bristol, England

J. Magn. Reson. (1980), 38(2), 207-14


A microprocessor-controlled pulse sequencer for diverse pulsed NMR expts. is described. The design is based on a first-in-first-out recycling memory which is loaded and triggered by computer software control. Sixteen output channels are provided for various synchronized functions.
