## Abstract An accurate measurement of the chemical shifts and the coupling constants of some disubstituted acetophenones has been made. The acetophenones studied contained nitro, bromo or amino groups substituted in either the 3,4 or 2,5 positions. For compounds with no substituent adjacent to the

## Abstract Interactions between mononucleoside and dinucleoside phosphates containing adenine and/or cytosine and Lβtryptophan have been studied at low pD by proton magnetic resonance (pmr) spectroscopy. The results of those studies indicate that, despite extensive protonation of ring positions, a
Proton nuclear magnetic resonance ('H n.m.r.) has been used to measure changes in the water-binding capacity of bed-moist brown coal lithotypes subjected to heat treatment. A rapid reduction in the coalwater interaction was found to occur at treatment temperatures > 420K. A Pale lithotype was found
Low-resolution proton nuclear magnetic resonance spectroscopy is a rapid and accurate technique for measuring moisture in coal and total solids in aqueous coal slurries. The adverse effects of ferromagnetic materials, such as magnetite, have been catered for by the use of a variable-gate technique.
