✦ Synopsis

This work shows how information from a number of solid-state 'H NMR experiments can be combined in a numerical model of a heterogeneous polymer system, which can then be iteratively optimised by varying a small number of parameters to fully represent the spin-diffusion and relaxation behaviour of the system. In this way useful information can be obtained not only about the size of the heterogeneities present, but also about the intrinsic relaxation behaviour of the different regions.

The proton spin diffusion rate in solid-state samples can be directly measured by using depolarization of rare spins in CP MAS NMR. In the slow decaying stage of the depolarization process, the magnetization of rigid protonated rare spins changes monoexponentially. This behavior can be reasonably de
