The monomer and excimer fluorescences of pyrene in dodecyl- and hexadecyl-trimethylammonium bromide micelles have been studied over the temperature range 297 to 325 K. An analysis of the quantum yield changes with concentration ...

Thermodynamic parameters for absorption of hydrogen by Ir/Pd alloys have been determined by p, c, T techniques in an u.h.v. system and by electrochemical measurements. The equilibrium solubility of hydrogen in these alloys ...

The radical cations and anions of a number of carbonyl containing polyenes of biological importance have been generated, and their absorptions characterised using pulse radiolysis techniques. The wavelength maxima of the ...

The relative rates of chlorine atom abstraction from alkyl chlorides by the trimethylsilyl radical have been studied by a competitive technique between 400 and 580 K in the gas phase. These results have been put on an ...

Pulse radiolysis of aqueous solutions of formic acid and formate ion in the pH range 0-13 shows (i) that the absorption spectrum of the carboxyl radical is constant between pH 2.5 and 13, but decreases in intensity between ...

The absorption spectrum of acridine in various solvents together with the fluorescence spectra and lifetimes in a rigid matrix confirms the presence of a weak, intrinsic π–π* emission in this material with its origin at ...

The activity coefficients of benzene, cyclohexane, n-pentane, n-hexane, n-heptane and n-octane in the involatile solvents, dinonyl phthalate and squalane, have been determined over a solute mole fraction range 0.05 to ...

Solubility isotherms for MnCl2 and NiCl2 in mixtures of pyridine with benzene and with o-dichlorobenzene have been determined at 20 and 30°C, and those of MnCl2 in mixtures of pyridine with chlorobenzene supplemented with ...

The effect of HCHO in reducing the induction periods of H2+ O2+ N2 mixtures at 500°C has been examined for a range of mixture composition, using HCHO concentrations in the range 0.05–1.0 %. Computer treatment shows that ...

We have measured the heat capacity of a zone refined sample of tetra-n-hexylammonium perchlorate (99.94 % pure, by analysis of the fusion curve). Values of the transition temperatures, enthalpies and entropies are: fusion ...
