The effect of alcohol concentration on the conductivities of solutions of n -propanol in c -hexane and iso-octane and of t -butanol in c -hexane following electron pulse irradiation, are quantitatively consistent with the existence of an equilibrium

The decay of solvated electrons, e-s in irradiated liquid alcohols can be separated into contributions from escaped ((e-s)esc) and spur ((e-s)spur) electrons. The decay of (e-s)spur in ethanol at 163 K approximates to the Warman-Asmus-Schuler functio

Laser-induced studies of the luminescence from Ru II (bipy) 2+ 3 in its charge-transfer excited state show that the quenching interaction with 9-methylanthracene is of a dynamic nature when both probe and quencher are associated with anionic micelles

A germanium photodiode, type L-4521 (Philco-Ford), and a silicon photodiode, type HP-4220 (Hewlett-Packard), have been examined with respect to their behaviour to light absorption signals as obtained in pulse radiolysis, and compared with a photomult

The presence of benzyl in 1-propanol, 2-propanol and ethanol glasses at 77 K markedly affects the changes which occur in the absorption spectra of the trapped electrons in the pure alcohols after their production by pulse radiolysis. The well known g

Observations of the solvation of electrons by methanol in methanol-2-methyltetrahydrofuran (MTHF) mixtures have been made at temperatures above and below the glass transition temperature. Results above the glass transition temperature are explained b

Previous observations on the spectral changes due to electrons in 1-propanol have been extended to 77 K. It is found that down to 118 K the decay in the I.R. and growth in the visible are first order and that from 118 to 313 K the rate constants fit

The rate constants for the reactions of electrons with biphenyl, pyrene, perylene and carbon tetrachloride in n-hexane can all be expressed by the relation k = 3·6(±1) × 10 14 exp [ −14,600(±1000) RT ] mol −1 dm 3 s −1 over the temperature

We have observed the “immediate” optical absorption spectra of excess electrons produced by pulse radiolysis of aliphatic hydrocarbons in the temperature range 295-77 K. In deuterated methyl-cyclohexane at 295 K we observe a broad absorption peak
