英文摘要	multiphoton ionization of the hydrogen,bonded pyrrole-water clusters (c4h5n)(n)(h2o)(m) is studied with a reflectron-time of flight mass spectrometer at 355 mn. 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 [(c4h5n)(x)(h2o)(y)](+), protonated cluster ions [(c4h5n)(x)(h2o)(y)](+) and dehydrogenated cluster ions [(c4h4n)(c4h5n)(x)(h2o)(y)](+). ab initio calculations of their structures, bond strengths, charge distributions and reaction energies are carried out. stable structures of these clusters are obtained from the calculations. a probable formation mechanism of the cluster ions [(c4h5n)(x)(h2o)(y)](+), [(c4h5n)(x)(h2o)(y)]h+ and [(c4h4n)(c4h5n)(x) (h2o)(y)](+) is supposed to be the ionization of clusters followed by dissociation.
