Description
Cryogenic ion trap vibrational spectroscopy is arguably one of the most powerful and widely applicable structural characterization tools for mass-selected clusters in the gas phase. Combined with the intense and widely tunable radiation from an infrared (IR) free electron laser it allows measuring vibrational spectra over nearly the complete IR spectral range, isomer-specifically, when necessary, and as a function of the cluster temperature. Recent advances are discussed, including (i) the characterization of methane activation by isomorphically-substituted binary (Al/Fe) metal oxide clusters, (ii) the identification of hydrogen-bond stretching vibrations in protonated water clusters and (iii) coupling microfluidics with infrared photodissociation spectroscopy.
