摘要：

A combination of IR depletion and one-color resonant two-photon ionization (1C-R2PI) spectroscopy is used for the first time to characterize mixed molecular clusters. We have studied the molecular aggregates (fluorobenzene).(methanol) and (fluorobenzene).(methanol)2 in the 9.6-mu-m region. The IR absorption spectra obtained are compared with those of the free methanol aggregates. From this, the structure of the neutral precursor of the intra-cluster reaction product anisole+ is identified as a complex of fluorobenzene and a methanol dimer. The disappearance of cluster-specific UV transitions in the R2PI spectra due to IR depletion is shown asa cross check of our results. We would like to recommend this method as a technique for the assignment of R2PI spectra of systems which decay quantitatively following ionization.
