The Radiolysis of Aqueous Acetonitrile: Compounds of Interest to Chemical Evolution Studies

Authors: I.G. Draganić, S. Jovanić, V. Niketić, Z.D. Draganić, Oxygen-free aqueous solutions of CH3CN (0.1 M, pH 6) were ex- posed to gamma rays from a 60Co source,the mixture of non volatile radiolytic products was fractionated and the fractions were analysed. Succinic,maleic, fumaric, malonic andpyruvic acids were identified. Glycol aldehyde,glucose and probably ribose were observed in the hydrolysate of fractionated…

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…
