摘要：

New observations of the infrared excitation and fragmentation of heterogeneous cluster ions of the form Y.X(n)+ are presented. By ensuring that IP(Y) > IP(X(n)) we show that it is possible to study the infrared spectroscopy of neutral chromophores (Y) in mass-selected clusters. By monitoring photofragmentation channels in conjunction with other aspects of cluster ion behaviour, such as intensity fluctuations (the presence of magic numbers), absorption spectra can be related to structure and decay dynamics. Preliminary results are presented for SF6.Ar(n)+, SF6.(CO2)n+, SF6.(NO)n+, and C2H4.(NO)n+.
