IR photofragmentation of the Phenyl Cation: Spectroscopy and Fragmentation Pathways
S. D. Wiersma, A. Candian, J. M. Bakker +5
We present the gas-phase infrared spectra of the phenyl cation, phenylium, in its perprotio CH and perdeutero CD forms, in the 260-1925 cm (5.2-38 m)…
Breakdown products of gaseous polycyclic aromatic hydrocarbons investigated with infrared ion spectroscopy
A. Petrignani, M. Vala, J. R. Eyler +5
We report on a common fragment ion formed during the electron-ionization-induced fragmentation of three different three-ring polycyclic aromatic hydrocarbons (PAHs), fluorene (C$_{…
Photolysis-induced scrambling of PAHs as a mechanism for deuterium storage
S. D. Wiersma, A. Candian, J. M. Bakker +4
Aim. We investigate the role of PAHs as a sink for deuterium in the interstellar medium and study UV photolysis as a potential process in the variations of the deuterium fractionat…
The infrared spectrum of protonated buckminsterfullerene, C60H+
Julianna Palotás, Jonathan Martens, Giel Berden +1
Although fullerenes have long been hypothesized to occur in interstellar environments, their actual unambiguous spectroscopic identification is of more recent date. C60, C70 and C6…
The observation of electron trap liberation in MgF doped with Yb using a two-color excitation experiment
P. S. Senanayake, J. P. R. Wells, M. F. Reid +3
We utilize the optical transitions of Yb excited by an ultraviolet optical parametric amplifier to probe electron trap liberation in MgF via the observation of a photo…
Impurity-trapped excitons and electron traps in CaF:Yb and SrF:Yb probed by transient photoluminescence enhancement
P. S. Senanayake, J. P. R. Wells, M. F. Reid +3
CaF:Yb and SrF:Yb crystals have been investigated by a two-color UV + IR transient photoluminescence enhancement technique. The enhancement gives information…
Transient photoluminescence enhancement as a probe of the structure of impurity-trapped excitons in CaF:Yb
Michael F. Reid, Pubudu S. Senanayake, Jon-Paul R. Wells +5
We demonstrate a direct measurement of the energy levels of impurity-trapped excitons in CaF:Yb. The radically different radiative decay rates of the lowest exciton stat…
