✦ Synopsis

The solvation dynamics of a rigid polar probe dissolved in highly polar aprotic solvents has been studied using time-resolved fluorescence techniques. We have observed good correlation between the characteristic solvation time ra and the microscopic relaxation time rM of the individual solvent molecules. Near the probe the "continuum" description of the solvent fails and a microscopic description is necessary.

## Abstract The rates of the diazo coupling reaction of 4‐toluenediazonium salts with N, N‐dimethylaniline in tetramethylene sulfone, acetonitrile, water, and nitromethane at 30°C are the same within a factor of 5. No significant influence of ‘gegenions’ (HSO or BF) was found. The results are expla
