Spectroscopic Evidence

The lowest excited singlet state (S1) of 4,4′-bipyridine (44BPY) has been studied in water and methanol by using pump-probe time-resolved resonance Raman spectroscopy in the picosecond time domain. Spectroscopic evidence for a disymmetric S1 structure with localization of the electronic excitation in one of the two pyridyl rings is given. The fast formation of the N-hydro radical 44BPYH• from the S1 state is clearly observed in methanol.

We studied the photodarkening effect in nanocrystalline CdS x Se1−x-doped glasses by pump-probe time-resolved Raman spectroscopy. A marked decrease in the phonon Raman intensities was observed when the photodarkened samples (commercial glass color filters) were pre-excited by the pump pulse. Such an intensity change was not observed for the fresh (unphotodarkened) samples. These findings have been interpreted in terms of a new photodarkening-induced state that traps the photoexcited electrons efficiently. The magnitude of the decrease in Raman intensities increased linearly with increasing selenium fraction, suggesting that the photodarkening energy state is related to the Se anion or corresponding vacancy on the surface of CdS x Se 1−x microcrystallites.
