Further information has been obtained on the electronic structure of 1,3,2-dithiazol-2-yl radicals. The structure has been well characterized previously except for positions 4 and 5 in the ring. We have obtained solution and powder ESR spectra of rad

The spin probes 1,1,3,3-tetramethylisoindolin-2-yloxyl (TMIO) and the sodium salt of its sulfonate, 1,1,3,3-tetramethylisoindolin-2-yloxyl-5-sulfonate (NaTMIOS) were used to monitor the microviscosity changes of water during starch gelatinization. In

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 isotop

Here we describe the improved synthesis and full characterisation, including W-band EPR analysis and X-ray crystallography, of an anionic isoindoline aminoxyl, 5-carboxy-1,1,3,3-tetramethylisoindolin-2-yloxyl 6 (CTMIO), which is more water soluble th

The first structural characterisation of a heterocyclic free radical in all phases has been achieved. 4,5-Bis(trifluoromethyl)-1,3,2-dithiazol-2-yl, [CF3CSNSCCF3]˙ 4d, a 7π radical, was prepared quantitatively on reduction of [4d][AsF6] with variou

New water-soluble and lipid-soluble spin probes suitable for the ESR investigation of the physical states and interactions of components of dough have been developed. This paper reports some preliminary findings on the suitability of these probes for

The stable free radical 1,1,3,3-tetramethylisoindolin-2-yloxyl (TMIO) has proved to be very suitable for use as a spin probe for a number of applications. Because it is soluble mainly in non-polar liquids, there is a need for new derivatives that can

A new ESR spin probe, sodium 1,1,3,3-tetrakis(trideuteromethyl)isoindolin-2- yloxyl-4-sulphonate, which is related to the extensively studied generic free radical 1,1,3,3-tetramethylisoindolin-2-yloxyl (TMIO), was synthesized. The latter has greater

For ESR studies of molecular rotation in liquids, it is desirable to match the spin probe as closely as possible to the solvent molecules. In this work the solvents were model lubricants whose overall motion has been characterized from carbon-13 NMR

The X-ray structures and proton and carbon-13 NMR spectra have been obtained for two dicyclohexyl esters and one tricyclohexyl ester: namely, di-2-methylcyclohexylsuccinate (D2MCS), dicyclohexyl-3,4-furandicarboxylate (DCFDC) and tricyclohexyl-1,2,3-
