The direct measurement of intramolecular electron transfer through detection of the electromagnetic (EM) waveform that is emitted during this process is reviewed. The waveform is detected in the time-domain via free-space electro-optic sampling and then related to the dynamics of

The capability of ammonium 18-molybdodiphosphate, (NH(4))(6)P(2)Mo(18)O(62) (Mo(18)(6-)), and ammonium 18-tungstodiphosphate, (NH(4))(6)P(2)W(18)O(62) (W(18)(6-)), to photochemically generate acid within films of a polymer with hydroxylic functional groups (namely, within poly(2-hydroxyethyl methacrylate) (PHEMA) films) is demonstrated. Upon UV irradiation, both 2:18 polyoxometalates (POMs)
