  1. 63. Specific Peptide-Bond Dissociation and Effects of a Phenyl Group of Some Peptide Model Molecules
    Dr Chen-Lin Liu (NSRRC)
    11/01/2019, 15:20
    Talk

    Near-edge X-ray absorption fine structure (NEXAFS) spectra at carbon, nitrogen, and oxygen K-edges of some peptide model molecules were measured utilizing an orthogonal acceleration time of flight mass spectrometer and were calculated with time-dependent density functional theory. Excitation source such as soft X-ray photons were from synchrotron radiation at Taiwan Light Source. The intensity...

  2. 59. Angry Aromatics: Substituted phenyl radical reactions probed with VUV synchrotron photoionization MS
    Dr Adam Trevitt (University of Wollongong)
    11/01/2019, 15:45
    Talk

    This presentation will describe our recent results probing the gas-phase radical reaction of various phenyl-radicals using synchrotron VUV photoionization mass spectrometry at the Advanced Light Source synchrotron.

    Functionalized aromatic molecules are prevalent in gas-phase reactive environments including combustion, atmospheric chemistry, and extra-terrestrial atmospheres but the...

  3. 3. Kinetics of the C$_3$H$_5$ + O$_2$ reaction investigated by photoionization using synchrotron radiation
    Mr Domenik Schleier (Institute for physical chemistry, University of Wuerzburg)
    11/01/2019, 16:10

    The kinetics of the ubiquitous allyl radical, C$_3$H$_5$, with molecular oxygen has been studied at the vacuum ultraviolet (VUV) beamline of the Swiss Light Source. The new CRF-PEPICO (Combustion Reactions Followed by Photoelectron Photoion Coincidence Spectroscopy) setup uses a slow flow tube reactor and enables the recording of threshold photoelectron spectra necessary for a background free,...

  4. 17. From grains to fragments: the study of polycyclic aromatic hydrocarbons in multiple radiation environments
    Dr Amanda Steber (Deutsches Elektronen-Synchrotron (DESY))
    11/01/2019, 16:25

    Polycyclic aromatic hydrocarbons (PAHs) are thought to play important roles in interstellar chemistry, from ice grain formation to catalyzing reactions; however, much about their photophysics and photochemistry is not yet known. Therefore, a multi-spectroscopic approach has been employed to study PAH fragmentation upon interaction with high radiation fields, PAH homo-clustering and clustering...

  5. 65. Design of the CRF-PEPICO
    Dr Daniel Rösch (Sandia National Laboratories)
    11/01/2019, 16:40
    Hot topic

    The CRF-PEPICO is a new double-velocity map imaging photoelectron photoion coincidence spectrometer that is currently being designed and built at Sandia. The purpose of this new instrument is to study fundamental gas phase reactions with transient species pertinent to combustion and atmospheric chemistry. This instrument will be used at the Advanced Light Source in Berkeley and at Sandia....
