✦ Synopsis

Transient Raman spectra of anisole cation (C6HJOCH$') and its para methyl derivative are reported. These radicals were prepared on the 100 ns time scale by electron transfer reactions in aqueous solution. The structural contents in these Raman spectra are much more extensive than in the recently studied REZP2CI spectra of phenetole cation (C6H,0GH5) + ' in molecular beams. On microsecond times, 4,4'dimethoxybenzene cation, (CsH,OCH&', was seen as a transient product of the reaction of anisole cation, but not ofpmethylanisole cation. The latter radical was observed to react in basic solutions with OH-at a rate constant of E5 x IO* M-l s-'.

## Abstract Absorption spectra of the superoxide ion have been studied in dimethylformamide (DMF) and acetonitrile (AN). It was found that the superoxide ion existed in equilibrium with an ion pair in AN (__K__~eq~ = 20__M__^−1^, Bu~4~N^+^ is the cation) and as “free” (solvated) ion in DMF. The add
