Description
Summary:NMR pulsed magnetic field gradient (?) methods to measure the self-diffusion coefficient rely upon an accurate measurement of ?. A technique has been developed which uses a deliberate mismatch between gradient pulses to obtain ? from the spin echo. This procedure provides an absolute measurement of self-diffusion coefficients in pulsed gradient experiments without the need for a reference sample.
