Under the short-gradient pulse (SGP) approximation, the pulsed-gradient spin-echo (PGSE) diffusion NMR signal from a restricted population of spins as a function of b-value or wavenumber q or gradient strength |G| shows a characteristic diffraction pattern (Callaghan Nature 1990). Moreover, the frequency of the diffraction pattern varies inversely with the size of the restricting pore, [...]
