Structural investigations with the dipolar demagnetizing field in solution NMR

We have established a simple Fourier-space relationship between the structure of heterogeneous samples and the amplitude of multiple spin echoes which arise in solution NMR as a result of the dipolar nuclear demagnetizing held. We have also developed a pulse sequence optimized for structure measurements in two component systems. The new formalism predicts the behavior of multiple spin echoes well and gives a very good description of experimental data obtained from simply structured samples.
