Multiphoton ionization of pyrrole-water mixed clusters

摘要

Multiphoton ionization of the hydrogen-bounded pyrrole-water clusters (C_4h_5n)_N (H_2O)_m is studied with a reflectron - time of flight mass spectrometer at 355 nm. With increasing partial concentration of pyrrole in a gas mixture source, a series of poly - pyrrole - water binary-mixed cluster ions can be observed, including unprotonated cluster ions [(C_4H_5N)_x (H_2O)_y]~+, protonated cluster ions [(C_4H_5N)_x (H_2O)_yH]~+ and dehydrogenated cluster ions [(C_4H_4N) (C_4H_5N)_x (H_2O)_y]~+.
