Excimer states in microhydrated adenine clusters

We present femtosecond pump-probe mass and photoelectron spectra for adenine (A) and microhydrated A m (H 2 O) n clusters. Three distinct relaxation processes of photoexcited electronic states were distinguished: in unhydrated A, relaxation of the optically bright ππ* state occurred via the dark nπ*...

Zusammenfassung:	We present femtosecond pump-probe mass and photoelectron spectra for adenine (A) and microhydrated A m (H 2 O) n clusters. Three distinct relaxation processes of photoexcited electronic states were distinguished: in unhydrated A, relaxation of the optically bright ππ* state occurred via the dark nπ* state with respective lifetimes of
