Radiative stabilization of the indenyl cation: Recurrent fluorescence in a closed-shell polycyclic aromatic hydrocarbon
James N. Bull, Arun Subramani, Chang Liu +5
Several small polycyclic aromatic hydrocarbons (PAHs) with closed-shell electronic structure have been identified in the cold, dark environment Taurus Molecular Cloud-1. We measure…
Cooling of gold cluster anions, Au, , in a cryogenic ion-beam storage ring
Klavs Hansen, Tian Weihao, Emma K. Anderson +9
We have measured the spontaneous and photo-induced decays of anionic gold clusters, Au, with sizes ranging from to 13, and 15. After production in a sputter ion sourc…
Resilience of small PAHs in interstellar clouds: Efficient stabilization of cyanonaphthalene by fast radiative cooling
Mark H. Stockett, James N. Bull, Henrik Cederquist +6
After decades of speculation and searching, astronomers have recently identified specific Polycyclic Aromatic Hydrocarbons (PAHs) in space. Remarkably, the observed abundance of cy…
Ultraslow radiative cooling of C ()
James N. Bull, Michael S. Scholz, Eduardo Carrascosa +8
Ultraslow radiative cooling lifetimes and adiabatic detachment energies for three astrochemically relevant anions, C (), are measured using the Double ElectroStatic Io…
Photodetachment and Photoreactions of Substituted Naphthalene Anions in a Tandem Ion Mobility Spectrometer
James N. Bull, Jack T. Buntine, Michael S. Scholz +4
Substituted naphthalene anions (deprotonated 2-naphthol and 6-hydroxy-2-naphthoic acid) are spectroscopically probed in a tandem drift tube ion mobility spectrometer (IMS). Target…
Absorption and luminescence spectroscopy of mass-selected Flavin Adenine Dinucleotide mono-anions
L. Giacomozzi, C. Kjær, J. Langeland Knudsen +3
We report the absorption profile of isolated Flavin Adenine Dinucleotide (FAD) mono-anions recorded using Photo-Induced Dissociation action spectroscopy. In this charge state, one…
