摘要: HCN is ubiquitous in extraterrestrial environments and central to current theories on the origin of early solar system organic compounds such as amino acids. These compounds, observed carbonaceous meteorites, were likely important and/or evolution life. As part our attempts understand origin(s) meteoritic CN–, we have analyzed 15N/14N isotopic composition gas released from water extracts Murchison meteorite found its value be near those terrestrial atmosphere. The findings, when evaluated viz-a-viz molecular abundances data suggest that formation could occurred during protracted alteration processes known affected mineralogy many asteroidal bodies their residence. This was an active synthetic stage, which involved simple gasses, molecules, presolar precursors, well mineral catalysts would lead molecules differing composition, including some with values.
