Cobalt‐59 NMR measurements were made on an aqueous solution of K3[Co(CN)6] with pressure as the main variable. We determined the effect of temperature and pressure (up to 5 kbar) on (i) the cobalt‐59 chemical shift, (ii) the carbon–cobalt‐59 isotope shift, (iii) the cobalt‐59–carbon‐13 coupling constant and (iv) the cobalt‐59 spin–lattice relaxation time. The marked effects of temperature and pressure on the chemical shift can be attributed to changes in the cobalt–carbon bond distance and are…

EXAFS investigations of temperature-dependent structure in cobalt-59 molecular NMR thermometers.

Extended X-ray absorption fine structure (EXAFS) spectroscopy for the first time is applied to five Co(iii) complexes to probe the exact variations in physical structure that produce the exceptional thermal sensitivity of the 59Co NMR chemical shift, implying that rich temperature-dependent structural variations define 59 Co NMR thermometry in macrocyclic complexes.

Simulation of 59Co NMR chemical shifts in aqueous solution.

The simulated solvent effects on geometries and delta(59Co) values are well reproduced by using a polarizable continuum model (PCM), based on optimization and perturbational evaluation of quantum-mechanical zero-point corrections.

Temperature and Pressure Dependence of the Co59 Nuclear Resonance Chemical Shift

We have measured with precision the temperature and pressure dependence of the Co59 nuclear resonance chemical shift (σ) in the octahedral cobalt complexes Co(NH3)63+, Co(CN)63—, and Co(NO2)63— in

Multi‐frequency, variable‐temperature and high‐pressure study of carbon‐13 spin—lattice relaxation in tetraoctyltin

Carbon‐13 NMR spin–lattice relaxation times, T1, and nuclear Overhauser effect data were obtained for neat tetra‐n‐octyltin at 22.5 and 100.6 MHz over a wide temperature range. T1 values were also

Isotope and temperature dependence of transition-metal shielding in complexes of the type M(XY)6

The temperature coefficients of the chemical shift of /sup 51/V in carbonyl complexes in solution are reported here. For transition metal nuclei the effects of rovibrational averaging can be obtained

Carbon‐13 NMR relaxation studies of some dicyclohexyl compounds at high pressure

Four dicyclohexyl compounds were investigated, one of which is a traction fluid and the remainder have related structures in which the cyclohexyl rings are separated by two or three carbon atoms.

A series of triphenylmethyl-substituted poly(acetylenes) has been studied by electron paramagnetic resonance (EPR) spectroscopy, and compared to poly(phenylacetylene)(PPA) as a reference material.

Nuclear Magnetic Resonance in Liquids under High Pressure

The work reported here is an application of free precession or ``spin echo'' techniques in nuclear magnetic resonance to a study of the properties of liquids under high pressure. The proton
