I wondered how transient solid-state NMR can be adopted to study the 1D diffusion pathway of of ions in a solid material? What is the relationship between the relaxation time (T1) and ionic diffusion? Any help would be greatly appreciated.
R1 (R1 = 1/T1) is sensitive to diffusive motion with jump rates for the range around Larmor frequency, which can be varied from 10 MHz to several hundred megahertz (long-range, bulk motion).
