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…
Dissociation and radiative stabilization of the indene cation: The nature of the C-H bond and astrochemical implications
M. H. Stockett, A. Subramani, C. Liu +5
Indene (CH) is the only polycyclic pure hydrocarbon identified in the interstellar medium to date, with an observed abundance orders of magnitude higher than predicted by a…
Stability of C Knockout Fragments from Femtoseconds to Infinity
Michael Gatchell, Naemi Florin, Suvasthika Indrajith +9
We have studied the stability of C anions as a function of time, from their formation on femtosecond timescales to their stabilization on second timescales and beyond, using…
Hydrogenated pyrene: Statistical single-carbon loss below the knockout threshold
Michael Wolf, Linda Giacomozzi, Michael Gatchell +5
An ongoing discussion revolves around the question of what effect hydrogenation has on carbon backbone fragmentation in Polycyclic Aromatic Hydrocarbons (PAHs). In order to shed mo…
Knockout driven fragmentation of porphyrins
Linda Giacomozzi, Michael Gatchell, Nathalie de Ruette +5
We have studied collisions between tetraphenylporphyrin cations and He or Ne at center-of-mass energies in the 50-110 eV range. The experimental results were interpreted in view of…
The threshold displacement energy of buckminsterfullerene C and formation of the endohedral defect fullerene He@C
M. H. Stockett, M. Wolf, M. Gatchell +3
We have measured the threshold center-of-mass kinetic energy for knocking out a single carbon atom from C in collisions with He. Combining this experimental result with cl…
