Are ionic liquids kosmotropic or chaotropic? An evaluation of available thermodynamic parameters for quantifying the ion kosmotropicity of ionic liquids

Instrumentation for the measurement of spin lattice relaxation times in liquids at pressures up to 5 kilobar and temperatures from −50 to 350°C is described. The experimental setup allows the use of the Fourier transform technique to obtain high resolution spectra and/or relaxation of chemically shifted nuclei under these extreme conditions.

Nuclear Magnetic Resonance Measurements at High Pressure

Pressure effects on the dynamic structure of liquids

The pressure dependence of the deuteron spin‐lattice relaxation times has been measured at 30°C in liquid pyridine‐4‐d1, fluorobenzene‐4‐d1, toluene‐4‐d1, chlorobenzene‐4‐d1, bromobenzene‐4‐d1, and benzylcyanide‐4‐d1. Viscosities at high pressures have also been measured at 30°C. In order to obtain information about the anisotropy of the intermolecular potential energy, the relaxation data were interpreted in terms of the parameter κ introduced originally by Kivelson. There is a correlation between the magnitude of κ and the van der Waals volume of the substituent on the benzene ring. From the results obtained it follows that molecular shape plays a decisive role in determining the degree of coupling between the rotational and translational motions in the molecular liquids investigated. Since the pressure dependence of the deuteron T1 has also been determined for fully deuterated pyridine, fluorobenzene, chlorobenzene, bromobenzene, and nitrobenzene, comparison of these data with those obtained for the mo...
