We have investigated gas-phase reactions of N(2D) with the most abundant hydrocarbons in the atmosphere of Titan by the crossed molecular beam technique. In all cases, molecular products containing a novel CN bond are formed, thus suggesting possible routes of formation of gas-phase nitriles in the atmosphere of Titan and primordial Earth. The same approach has been recently extended to the study of radical–radical reactions, such as the reaction of atomic oxygen with the CH3 and C3H5 radicals. Products other than those already considered in the modeling of planetary atmospheres and interstellar medium have been identified.

Abstract
We have investigated gas-phase reactions of N(2D) with the most abundant hydrocarbons in the atmosphere of Titan by the crossed molecular beam technique. In all cases, molecular products containing a novel CN bond are formed, thus suggesting possible routes of formation of gas-phase nitriles in the atmosphere of Titan and primordial Earth. The same approach has been recently extended to the study of radical–radical reactions, such as the reaction of atomic oxygen with the CH3 and C3H5 radicals. Products other than those already considered in the modeling of planetary atmospheres and interstellar medium have been identified.File in questo prodotto:
