Hole burning in well-defined noise fields: Motional narrowing

Abstract

Hole burning in the proton NMR line in water was observed in well-defined noise fields. The hole shape was measured in two-state and Gaussian noise fields. The jumping-time dependences of the hole shape were well explained by the theory of motional narrowing and the conventional stochastic theory of relaxation. This approach is very useful for the experimental test of relaxation theories.
