An experimental photochemistry study involving gas-and solid-phase amino acids (glycine, DL-valine, DL-proline) and nucleobases (adenine and uracil) under soft X-rays was …

We present a combined experimental and theoretical work on the ionization energies of polyacetylene–organic molecules considered as important building blocks to form polycyclic …
We investigate the effects produced mainly by broadband soft X-rays up to 2 keV (plus fast (∼ keV) photoelectrons and low-energy (∼ eV) induced secondary electrons) in the ice …

The infrared signatures of polycyclic aromatic hydrocarbons (PAHs) are observed in a variety of astrophysical objects, including the circumnuclear medium of active galactic nuclei …
We present a computational investigation into the fragmentation pathways of ethanolamine (C2H7NO, EtA), propanol (C3H8O, PrO), butanenitrile (C4H7N, BuN), and glycolamide …

In this work, broad-band soft X-ray (6–2000 eV) was employed to irradiate frozen acetonitrile CH3CN, at the temperature 13 K, with different photon fluences up to 1.5× 1018 photons cm …
Polycyclic aromatic hydrocarbons (PAHs), comprised of fused benzene (C 6 H 6) rings, emit infrared radiation (3–12 μm) due to the vibrational transitions of the C–H bonds of the …
The abundances of molecules and ions depend on the mechanisms of their formation and destruction that can occur both in the gas phase and in the condensed phase on grain …
The methyl formate molecule (HCOOCH3) is one of the most abundant molecules observed in hot molecular cores. Together with acetic acid and the sugar glycolaldehyde, these …
