NMR Studies on the Temperature-Dependent Dynamics of Confined Water

open access: yes, 2014
We use $^2$H NMR to study the rotational motion of supercooled water in silica pores of various diameters, specifically, in the MCM-41 materials C10, C12, and C14. Combination of spin-lattice relaxation, line-shape, and stimulated-echo analyses allows us
