The Gamma Irradiation of Aqueous Solutions of Urea. Implications for Chemical Evolution

Authors: R. Navarro-González, A. Negrón-Mendoza, E. Chacón 0.05moledm-3,Oz-free aqueous solutions of urea were studies after receiving various doses of 6°Co gamma rays(0.14-600kGy). Urea was found to be relatively stable under radiation; its radiation chemical yield of decomposition was 0.47. Hydrogen (G=0.50), carbon dioxide (G=0.44), ammonia (G=0.22), oxalic acid (G=0.0054), malonic acid (G=0.000064)and three unidentified oligomers were found to be the…

Radiolysis of methanol vapour

Authors: J. H. Baxendale, R.D. Sedgwick The yields of hydrogen, formaldehyde, ethylene glycol, methane and carbon monoxide from the radiolysis of methanol vapour have been measured and also those of H2 and HD from CH3OD. These have been correlated with the ions observed in the mass spectra. Benzene decreases the yields of hydrogen and formaldehyde and the effect is attributed…

Pulse Radiolysis Studies II. Transient Spectra and Rate Processes in Irradiated Ethanol and Aqueous Ethanol Solution

Authors: I. A. Taub, L. M. Dorfman The radiation chemistry of deaerated aqueous ethanol and deaerated liquid ethanol has been studied by the pulse radiolysis technique. The same transient absorption spectrum, showing a broad weak absorption at about 290 mU and stronger narrow peaks at 266, 257 and 247 mU, has been observed in both systems. It is concluded that…

Formation of Acetamide in Interstellar Medium

Authors: L. Foo, A. Surànyi, A. Guljas, M. Szőri, J. J. Villar, B. Viskolcz, I. G. Csizmadia, A. Rágyanszki, B. Fiser Acetamide (C2H5NO) is the largest molecule containing a peptide bond, which is an amine (-NH2) group bonded to a carbonyl (C = O) group, that has yet been detected in interstellar medium (ISM). It is also considered to be…
