The insoluble organic matter (IOM) contained in carbonaceous chondrites has witnessed a diverse suite of processes possibly starting from the evolution of the parent molecular cloud down to the protosolar nebula and finally to asteroidal processes that occurred on the chondrites’ parent bodies. Laser desorption coupled with ultra-high-resolution mass spectrometry reveals that the IOM of the Paris meteorite releases a large diversity of molecules. Various molecular families ranging from hydrogenated amorphous carbon to CHNOS aromatic molecules were detected with heteroatoms (nitrogen, oxygen, and sulfur) mainly incorporated within aromatic structures. Molecules bearing nitrogen atoms present a significant variation in aromaticity. These unprecedented results allow the proposal that small molecules bearing heteroatoms could be trapped in the large macromolecular network of the IOM by hydrophobic interactions. This molecular diversity could originate from different sources, such as...

陨石不溶有机物质中前所未有的分子多样性：巴黎陨石案

碳质球粒陨石中所含的不溶有机物（IOM）经历了一系列不同的过程，可能从母体分子云的演化到原生质星云，最后到发生在球粒陨石母体上的小行星过程。激光解吸结合超高分辨率质谱表明，巴黎陨石的IOM释放出大量的分子。使用主要结合在芳族结构中的杂原子（氮，氧和硫）检测到了从氢化无定形碳到CHNOS芳族分子的各种分子家族。带有氮原子的分子在芳香性方面存在显着变化。这些空前的结果提出了这样的建议，即带有杂原子的小分子可以通过疏水相互作用被困在IOM的大分子网络中。这种分子多样性可能来自不同的来源，例如...
