The Significant Role of Hydrogen in the Formation of Silicon Carbide in Evolved Stars
Guillermo Tajuelo-Castilla, Gonzalo Santoro, Lidia Martínez +13
Cosmic dust is mainly formed in the atmospheres of evolved stars. In carbon rich stars, amorphous carbon along with silicon carbide are the main constituents of dust grains yet the…
Gas-phase spectroscopy of photostable PAH ions from the mid- to far-infrared
Sandra D. Wiersma, Alessandra Candian, Joost M. Bakker +1
We present gas-phase InfraRed Multiple Photon Dissociation (IRMPD) spectroscopy of cationic phenanthrene, pyrene, and perylene over the 1001700 cm (6-95 m) spectral ra…
IRMPD spectroscopy of a PAH cation using FELICE: The infrared spectrum and photodissociation of dibenzo[a,l]pyrene
Sandra Denise Wiersma, Alessandra Candian, Mathias Rapacioli +1
We present the experimental InfraRed Multiple Photon Dissociation (IRMPD) spectrum and fragmentation mass spectrum of the irregular, cationic PAH dibenzo[a,l]pyrene (CH$_{14…
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)…
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…
