Spectroscopy of Ions and Their Clusters
Abstract
Based upon mass spectrometric evidence as well as indirect speculations, molecular ions and their clusters have long been recognized as playing important roles in the chemistry of the earth's atmosphere. However, the (non-mass) spectroscopy of all large ions is difficult, with the spectroscopy of cluster ions being essentially non-existent. We are constructing a unique apparatus for the spectroscopic study of large ions, particularly ionic clusters. This apparatus allows the combination of laser induced fluorescence characterization of ions and their clusters while simultaneously identifying them by their time-of-flight mass spectra. This apparatus can make exciting contributions to our knowledge of how the electronic spectra of ions change as neutral species are clustered about them. Similarly, the manner in which such clusters react to radiation, i.e. fragmentation, fluorescence, etc., can be detailed by such experiments. Keywords: Laser induced fluorescence, Chemical physics, Spectroscopy, Molecular ions, Atmospheric chemistry, Cold plasma, Clusters, Combustion environments.
