Soluble polycyclic aromatic hydrocarbons (PAHs) have been measured in Mukundpura (MK) CM2 carbonaceous chondrite using Gas Chromatography-Mass Spectrometry (GC-MS). The data show high yields of PAHs with the presence of 2, 3, and 4 ring polycyclic aromatic hydrocarbons along with heterocyclic nitrogen and sulfur-containing compounds. MK also shows the presence of significant amount of alkylation products. The distribution and relative abundances of PAHs in the MK are discussed in context of its petrographic grade and correlation with aqueous alteration.

Mukundpura（CM2）球粒陨石中的多环芳烃

已使用气相色谱-质谱法（GC-MS）在Mukundpura（MK）CM2碳质球粒陨石中测量了可溶性多环芳烃（PAH）。数据显示存在2、3和4环多环芳烃以及杂环含氮和含硫化合物时，PAHs的收率很高。MK还表明存在大量烷基化产物。在岩石学等级及其与含水蚀变的相关性的背景下，讨论了MK中PAHs的分布和相对丰度。
