The 2D 1H NMR correlation maps of longitudinal (T1) and transverse (T2) relaxation times prove sensitive in monitoring the distribution of magnetic pore environments in porous systems. The comparison with Mössbauer data establishes a direct correspondence between the susceptibility-induced effects observed in the T1–T2 maps for pore–filling water and the Fe(III)-bearing magnetic compounds.

Abstract
The 2D 1H NMR correlation maps of longitudinal (T1) and transverse (T2) relaxation times prove sensitive in monitoring the distribution of magnetic pore environments in porous systems. The comparison with Mössbauer data establishes a direct correspondence between the susceptibility-induced effects observed in the T1–T2 maps for pore–filling water and the Fe(III)-bearing magnetic compounds.File in questo prodotto:
