- •
Proton time-domain NMR is sensitive to mobility differences in heterogeneous materials.
- •
Techniques for reliable component decomposition based upon filters are reviewed.
- •
Properties and drawbacks of different magnetization filters are addressed in detail.
- •
Spin diffusion coefficients are determined for poly(ϵ-caprolactone).
- •
Differences in spin diffusion coefficients under static vs MAS conditions are discussed.
