WebSolvated electrons have also been observed in several other solvents. The bottleneck of the observation of the solvated electrons is their (usually very short) lifetimes. While the ammoniated electron persists for days, the solvated electron in water (hydrated electron) is a short living species surviving only several microseconds.
