Proton transfer and isotope-induced reaction in aniline cluster ions

Popis výsledku v původním jazyce

The proton transfer (PT) and other intraclusters reactions occurring after electron ionization of aniline clusters (PhNH2)N are investigated by the time-of-flight mass spectrometry. The mass spectra are recorded for different expansion conditions leadingto the generation of different cluster sizes. Several fragment ions are shown to originate from intracluster reactions, namely, [Ph]+, [PhNH3]+ and [Ph?N?Ph]+. Reaction schemes are proposed for these ions starting with the PT process. The mass region beyond the monomer mass is dominated by cluster ions (PhNH2)n + accompanied by satellites with H and +2H. In experiments with deuterated species, new fragment ions are identified. The aniline isotopomer d5-PhNH2 yields the fragment ions (PhNH2)n.(N?Ph? NH2)+. Analogical series is observed in experiments with d7-PhND2, and additional fragments occur corresponding to (PhND2)n. (D2N?ND?Ph?ND?ND2)+ ions. The possible reaction pathways to these ions and the unusual isotope effects are discussed
