Crossed beams and theoretical study on two reactions relevant to Titan's atmosphere: N(2D) + propyne and N(2D) + allene

Description

We have investigated the N(2D) + CH3CCH (propyne) reaction and the N(2D) + H2CCCH2 (allene) reaction to elucidate the nature of the primary products and the micromechanism at play [Experimental] by coupling the crossed molecular beams (CMB) technique with mass spectrometric detection and time-of-flight analysis (angular distribution and tof spectra)
[Theoretical] with electronic structure calculations of stationary points and product energetics (potential energy surface, PES). Furthermore, RRKM statistical calculations were performed to derive the product branching ratios (BRs) under the conditions of the present experiments and of the atmosphere of Titan.
