On the Radiolysis of Ethylene Ices by Energetic Electrons and Implications to the Extraterrestrial Hydrocarbon Chemistry

Authors: L. Zhou, S. Maity, M. Abplanalp, A. Turner, R.I. Kaiser The chemical processing of ethylene ices (C2H4) by energetic electrons was investigated at 11 K to simulate the energy transfer processes and synthesis of new molecules induced by secondary electrons generated in the track of galactic cosmic ray particles. A combination of Fourier transform infrared spectrometry (solid state) and…

Spectroscopic investigations of high-energy-density plasma transformations in a simulated early reducing atmosphere containing methane,

Authors: M. Civiš, M. Ferus, A. Knížek, P. Kubelik, M. Kamas, P. Španel, K. Drahina, V. Shestivska, L. Juha, P. Skrehot, V. Laitl, S. Civiš Large-scale plasma was created in gas mixtures containing methane using high-power laser-induced dielectric breakdown (LIDB). The composition of the mixtures corresponded to a cometary and/or meteoritic impact into the early atmosphere of either Titan or…

Cyanomethylene Formation from the Reaction of Excited Nitrogen Atoms with Acetylene: A Crossed Beam and ab Initio Study

Authors: N. Balucani, M. Alagia, L. Cartechini, P. Casavecchia, G. G. Volpi, K. Sato, T. Takayanagi, Y. Kurosaki The reaction of excited nitrogen atoms, N(2D), with the simplest alkyne, C2H2, was investigated for the first time under single-collision conditions in crossed beam experiments with mass spectrometric detection. The experimental results combined with electronic structure calculations and RRKM predictions allow us…
