Abstract

Water ²H NMR signal on the surface of nano-silica material, MCM-41, consists of two overlapping resonances. The ²H water spectrum shows a superposition of a Lorentzian line shape and the familiar NMR powder pattern line shape, indicating the existence of two spin components. Chemical exchange occurs between these two groups. Decomposition of the two signals is a crucial starting point for study the exchange process. In this article we have determined these spin component populations along with other important parameters for the ²H water NMR signal over a temperature range between 223 K and 343 K.
