Abstract: Experiments to show the reverse situation where T(super IS) > T(sub 1p)(super I), slow CP regime may occur through the NMR cross-polarization (CP) measurements is seen. Examples are given on silica gel and calcium silicate hydrate samples for which the proper analysis allows a deeper insight into the nature of the protonated surfaces.
