A range of analytical techniques has been used to characterise the chemistry and morphology of a diesel-engine and an exhaust soot, and a comparison made with a selection of commercial carbon blacks. Significant differences have been observed in the

A novel n.m.r. method for determining the aromaticity of coal has been evaluated. Polarization transfer from the paramagnetic electrons is used to enhance the intensity of the 13 C n.m.r. spectrum. Analysis of five samples of Gondwana bituminous stea

207 Pb spin-lattice relaxation ( T 1 ) studies at magnetic fields of 2.35 and 7.05 T of Pb(NO 3 ) 2 , PbMe, and PbMe 3 Cl indicate field dependence only for PbMe 3 Cl. Variable-temperature studies on this compound demonstrate the interplay between th

We report the first demonstration of spatial mapping of proton chemical shifts using a modified projection reconstruction/echo-planar hybrid technique (PREP) ( 1, 2). PREP is a fast chemical-shift imaging technique which allows the generation of a fu

199 Hg spin-lattice relaxation times ( T 1 ) have been measured for diphenylmercury at magnetic fields of 2.35 and 7.05 T. T 1 was nine times shorter at the higher field (0.033 sec at 310 K) than at the lower field (0.30 sec), showing relaxation by c

syn-(1-Methylpentadienyl)iron tricarbonyl fluoroborate reacts with basic alumina to give initially syn-(1-vinyobutadiene)iron tricarbonyl. Prolonged reaction results in the formation of a dimer, C18H16Fe2O6, and small amounts of higher molecular weig

In this work, the lower molecular weight carboxylic acids, formic, acetic, propionic, n-butyric, isobutric and trimethylacetic have been studied to find, firstly, whether there is any trend in thermodynamic properties due to mass or structure of the

The infrared spectrum of the vapor from 50 to 4000 cm−1 and the Raman spectrum of the liquid with polarizations have been obtained for divinyl ether. These data indicate the presence of two rotational isomers. The more stable isomer has Cs symmetry
