Collisional excitation of propyne (CHCCH) by He atoms
M. Ben Khalifa, B. Darna, J. Loreau
A detailed interpretation of the detected emission lines of environments in which propyne (or methyl acetylene, CHCCH) is observed requires a knowledge of its collisional rate…
Rotational excitation of interstellar benzonitrile by helium atoms
M. Ben Khalifa, J. Loreau
Interstellar aromatic molecules such as polycyclic aromatic hydrocarbons and polycyclic nitrogen and oxygen bearing molecules are thought to be abundant in the interstellar medium.…
Collisional excitation of methyl (iso)cyanide by He atoms: rate coefficients and isomerism effects
M. Ben Khalifa, P. J. Dagdigian, J. Loreau
Among all closed-shell species observed in molecular clouds, molecules with C symmetry play a crucial role, as their rotational spectroscopy allows them to behave as a gas t…
Interaction of CHCN and CHNC with He : potential energy surfaces and low-energy scattering
Malek Ben Khalifa, Paul J. Dagdigian, Jérôme Loreau
Several nitrogen-bearing molecules, such as methyl cyanide (or acetonitrile, CHCN) and methyl isocyanide (CHNC) of interest here, have been observed in various astrophysica…
Deuteration of c-CH towards the pre-stellar core L1544
K. Giers, S. Spezzano, F. Alves +7
Context: In the centre of pre-stellar cores, the deuterium fractionation is enhanced due to the cold temperatures and high densities. Therefore, the chemistry of deuterated molecul…
