Organic Synthesis by Quench Reactionsestigated for the study of chemical evolution..A mixture of gaseous methane and ammonia over a water surface was exposed to an arc discharge between an electrode and the water surface. This discharge served as a source of dissociated, ionized and excited atomic and molecular species..Various organic

Shock Synthesis of Amino Acids IIparately in the non-homogeneous gas during the high temperature period and recombine with ammonia during the thermal quench period, to form α-amino nitriles. The α -amino nitriles are either hydrolyzed by excess water vapor during the quench period or emerge as such after the reaction is completed.

NMR Studies of Prebiotic Polypeptidesitutional characterization of homo- and co-polymers containing Asp and Glu residues, whose role is essential for the formation of the so-called proteinoids. Contrary to the literature data based on chemical degradation, nmr studies show conclusively that in thermal poly-aspartic acid only .-peptide
