Hydrogenation of solid hydrogen cyanide HCN and methanimine CH2NH at low temperature

Context. Hydrogenation reactions dominate grain surface chemistry in dense molecular clouds and lead to the formation of complex saturated molecules in the interstellar medium. Aims. We investigate…

A rigorous detection of interstellar CH3NCO: An important missing species in astrochemical networks.

The recent analysis of the composition of the frozen surface of comet 67P/Churyumov-Gerasimenko has revealed a significant number of complex organic molecules. Methyl isocyanate (CH3NCO) is one of…

Temperature dependence of HC3N, C6H2, and C4N2 mid-UV absorption coefficients. Application to the interpretation of Titan's atmospheric spectra

Three organic compounds (HC3N, C6H2, and C4N2) relevant of Titan's atmosphere have been studied within the framework of the SIPAT (Spectroscopie UV d'Intérêt Prébiologique dans l'Atmosphère de Titan)…

IR Spectrum of C8H2: Integrated Band Intensities and Some Observational Implications

Polyynes are of astrophysical interest since they appear to be involved in organic chemistry in very different mediums. In Titan's atmosphere, the lightest polyyne, C4H2, was detected by Voyager.…
