    • Competitive absorption by the quencher at the laser wavelength is a problem at high concentrations of some of these aromatics. Spectra were recorded at 0.14 M anisole, which corresponds to ∼80-90% quenching of 2. However, 2 still has a lifetime of several microseconds under these conditions, which may make it difficult to detect transients with similar or shorter lifetimes. Spectra for mesitylene and benzhydrol could only be measured at concentrations for which there was considerably less quenching of the initial zwitterion.
