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.

Contrary to the literature data based on chemical degradation, nmr studies show conclusively that in thermal poly-aspartic acid only .-peptide
