NMR spectroscopy study of local correlations in water
Journal of Chemical Physics
Using nuclear magnetic resonance we study the dynamics of the hydrogen bond (HB) sub-domains in bulk and emulsified water across a wide temperature range that includes the supercooled regime. We measure the proton spin-lattice T 1 and spin-spin T 2 relaxation times to understand the hydrophilic interactions that determine the properties of water. We use (i) the Bloembergen, Purcell, and Pound approach that focuses on a single characteristic correlation time ⌧ c , and (ii) the Powles and Hubbarddoi:10.1063/1.4968589 pmid:28799351 fatcat:2hv73x6vq5bufchmirn73nyskq
