A simplification of traditional nuclear magnetic resonance diffusion experiments was described which was suitable for treating time-dependent diffusion coefficients. It was shown that, by setting the experimental attenuation parameter to a fixed value, it was possible to observe the characteristic variation in the normalized echo amplitude in restricted diffusion conditions, and to construct normalized experimental curves without actually performing measurements of the diffusion coefficient at all of the relevant times. This led to marked experimental time reductions.
