Abstract

H atoms have been created by the photolysis of H2S. These then initiated reactions in mixtures involving acetylene-ammonia-water and ethylene-ammonia-water. In the case of the acetylene system, the products consisted of two amino acids, ethylene and a group of primarily cyclic thio-compounds, but no free sulfur. In the case of the ethylene systems, seven amino acids, including an aromatic one, ethane, free sulfur, and a group of solely linear thio-compounds were produced. Total quantum yields for the production of amino acids were approximately 3 x 10(-5) and approximately 2 x 10(-4) with ethylene and acetylene respectively as carbon substrates. Consideration is given of the mechanism for the formation of some of the products and implications regarding planetary atmosphere chemistry, particularly that of Jupiter, are explored.

摘要

氢原子由硫化氢的光解作用产生。这些氢原子随后引发了涉及乙炔 - 氨 - 水和乙烯 - 氨 - 水混合物的反应。在乙炔体系中,产物包括两种氨基酸、乙烯和一组主要为环状硫化合物,但没有游离硫。在乙烯体系中,产生了七种氨基酸,包括一种芳香族氨基酸、乙烷、游离硫和一组仅为线性硫化合物。以乙烯和乙炔分别作为碳底物时,氨基酸生成的总量子产率分别约为3×10⁻⁵和约2×10⁻⁴。文中考虑了一些产物的形成机制,并探讨了其对行星大气化学,特别是木星大气化学的影响。
