Microhydration Effects on the Ultrafast Photodynamics of Cytosine: Evidences for a Possible Hydration-Site Dependence

Ultrafast excited‐state deactivation dynamics of small cytosine (Cy) and 1‐methylcytosine (1mCy) microhydrates, Cy⋅(H2O)1‐3 and 1mCy⋅(H2O)1,2, produced in a supersonic expansion have been studied by mass‐selected femtosecond pump–probe photoionization spectroscopy at about 267 nm excitation. The see...
