STRUCTURAL INVESTIGATIONS WITH THE DIPOLAR DEMAGNETIZING FIELD IN SOLUTION NMR

We have established a simple Fourier-space relationship between the st ructure of heterogeneous samples and the amplitude of multiple spin ec hoes which arise in solution NMR as a result of the dipolar nuclear de magnetizing held. We have also developed a pulse sequence optimized fo r structure measurements in two component systems. The new formalism p redicts the behavior of multiple spin echoes well and gives a very goo d description of experimental data obtained from simply structured sam ples.
