Infrared spectroscopy of gas-phase zirconium oxide clusters

Gas-phase zirconium oxide clusters are resonantly excited using IR radiation from a free electron laser. At sufficiently large excitation fluences, clusters with a composition Zr n O 2 n−1 are observed to thermally emit electrons. Scanning the IR wavelength while monitoring the ion yield gives IR sp...

Summary:Gas-phase zirconium oxide clusters are resonantly excited using IR radiation from a free electron laser. At sufficiently large excitation fluences, clusters with a composition Zr n O 2 n−1 are observed to thermally emit electrons. Scanning the IR wavelength while monitoring the ion yield gives IR spectra of the clusters. For all clusters, resonances are observed between 600 and 700 cm −1 and the spectra are almost independent of cluster size.
