Fig. 3.

EPSR fit (line) to the total scattering data from wet MCM41 at 298 K (circles) over three different scales of intensity and Q. Row (a) shows the fits to the data with absorbed H₂O water molecules, while row (b) shows the fit to the data with D₂O water molecules.The left-hand plot shows the (1 0 0) Bragg peak, the middle plot shows the (1 1 0), (2 0 0) and higher order Bragg peaks, while the right-hand plot shows the wider Q region beyond Q = 1Å⁻¹.
