Nuclear Magnetic Resonance in Liquids under High Pressure

摘要: The work reported here is an application of free precession or ``spin echo'' techniques in nuclear magnetic resonance to a study the properties liquids under high pressure. proton relaxation time T1 was measured as function pressure, over range 1 10 000 atmospheres, for six liquids: water, n‐pentane, n‐hexane, toluene, ethyl iodide, and methyl iodide. In addition time, normalized values D(P)/D(1) self‐diffusion constant were pressure water iodide.In each liquid decreases with increasing However, comparison observed variation Bridgman's data on viscosity η shows all cases (except that iodide which no are available) not simply proportional 1/η, but instead T1η increases Similarly, diffusion D varies such way T1/D pre...
