摘要：

We report on a molecular beam experiment combining the methods of IR depletion and resonant two-photon ionization (R2PI) spectroscopy. Mixed molecular aggregates of fluorobenzene (FB) and methanol (MeOH), viz. (FB)(MeOH) and (FB MeOH)2, are characterized. After photoionization these clusters show size-dependent reaction channels. By comparing our IR depletion spectra with those of free methanol aggregates an assignment of the neutral precursors is feasible. For the system in question, the (1 : 2) aggregate is identified as the neutral precursor for both, the fragmentation product (1 : 1)+ and the reaction product anisole+.
