The problems that have to be addressed in designing suitable spin probes are manifold. In this article it will be shown that some the properties the probes need to possess are (i) a simple EMR spectrum (in some types of imaging or oximetry a single l

We investigate the NMR relaxation of solvent nuclei in non viscous paramagnetic solutions, in the case where the electronic spin of the paramagnetic species is submitted to an internal hyperfine fi...

The power of EPR spectroscopy as a structural probe of free radicals derives from solid-state studies, particularly of single-crystal specimens, that provide detailed information on tensor components and their principal directions. A review of EPR st

Multi-frequency relaxation studies combined with the ‘two-step’ and ‘three-step’ models for molecular motion have been applied to a range of anionic surfactant molecules. From the internal dynamic parameters (τf and S) conclusions have been

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 measured at 25.16 MHz at pressures up to 211 MPa. T

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. Carbon-13 spin-lattice relaxation times have been meas

The design and construction of an electroviscometer, which can be constructed in a good workshop, is presented; it is intended for use with high-performance electro-rheological (ER) fluids. The instrument allows several properties of ER fluids to be

The 13C nuclear relaxation behaviour of n-alkyl chains in a variety of compounds can be described in terms of two relaxation times, one for tumbling (τc) and one for each carbon nucleus for the internal motions (τc). Relaxation data for the quatern
