 Title: INFRARED PHOTODISSOCIATION SPECTROSCOPY OF THE EXOTIC H6+ CATION IN THE GAS PHASE Author(s): McDonald II, David C Contributor(s): Duncan, Michael A.; Wagner, J. Philipp Subject(s): Mini-symposium: New Ways of Understanding Molecular Spectra Abstract: H$_{6}$$^{+} is generated in a supersonic expansion via pulsed electrical discharge of hydrogen. H_{n}$$^{+}$ clusters are extracted into a reflectron time-of-flight mass spectrometer and probed with infrared photodissociation spectroscopy (IRPD) in the 2050 – 4600 cm$^{-1}$ region. H$_{6}$$^{+} was mass selected and found to have three distinct photodissociation channels by loss of one hydrogen atom, one hydrogen molecule or both. Each channel results in different spectra as a result of mode specific dissociation channels. The ground ^{2}D_{2d} state is 4 kcal/mol lower in energy than the ^{2}c_{S} state with a 7 kcal/mol barrier. We believe we are probing the ^{2}D_{2d} structure with the three H_{m}$$^{+}$ (m=3,4,5) fragment channels as a result of rapid interconversion between the two states after IR photon absorption.
