摘要: Abstract A simple technique for solving the Torrey–Bloch equations appearing in calculation of NMR signal under gradient fields is presented. It applicable to arbitrary time dependence field initial distribution spins, and spin motion on discrete lattices as well continuum conditions unrestricted diffusion. Known results are recovered particular cases new The lattice shown be similar known restricted diffusion continuum. Also presented a surprising equivalence between two-site hopping model earlier expressions spins undergoing
