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