Reaction Mechanisms and Kinetics of CN and CCH with H2CS: Implications for Interstellar Sulfur Chemistry
Boutheïna Kerkeni, Ghofrane Ouerfelli, Nicole Feautrier +1
We report an ab initio and master-equation investigation of the gas-phase reactions of thioformaldehyde (H2CS) with CN and CCH radicals, motivated by the recent detection of the S-…

Hydroxylated Mg-rich amorphous silicates as catalysts for molecular hydrogen formation in the interstellar medium
V. Mennella, T. Suhasaria, B. Kerkeni +1
We present results from an experimental study on the interaction of atomic deuterium with Mg-rich amorphous enstatite and forsterite type silicates. Infrared spectroscopy was used…
