2-d ESR diffusion coefficient imaging with the projection reconstruction method.
The static gradient spin echo (SGSE) of the conduction electron spins in a quasi-one dimensional organic conductor is analyzed by simulation and for a microstructured (fluoranthene)(2)PF(6) single crystal. It is shown that useful two-dimensional magnetic resonance images of the diffusion coefficient (mobility) D can be obtained from pixel-by-pixel analysis of the signal decay with pulse separation tau, adopting the projection reconstruction (PR) method for signal generation.
