Studies on NMR Method for Selfdiffusion Measurement in Solution

Two novel 3D pulse sequences using pulsed field gradient are proposed for self-diffusion measurement in solution. They are modified from the stimulated echo sequence by incorporating the pulse sequence for spinlattice relaxation measurements. These pulse sequences can be used as the method for obtaining the self-diffusion coefficient and spin-lattice relaxation time in one experiment. In addition, the results show that there are no cross interaction between the spin relaxation and the self-diffusion in solution of simple molecules.
