Abstract
The NMR relaxation behavior of the proton magnetization in adsorbed water is investigated. Longitudinal as well as transverse relaxation of the adsorbed water as a whole shows a distinct nonexponentiality and the nature of this nonexponentiality is studied. Different methods of fitting distribution of relaxation times are examined and various simulated and experimental decay curves are submitted to these fitting methods. The results of these fittings clearly indicate that both the longitudinal and the transverse relaxation of the proton magnetization in adsorbed water is related to two or three discrete components and that there is certainly no broad distribution of relaxation times present in these water-adsorbent systems.
