等离子体放电辐照进行了甲烷笼形物预计在太阳系外的卫星和彗星核,也照射冰制备的其他组合的H{sub 2}O与CH{sub 4},C{sub 2}H{sub 6},或C{sub 2}H{sub 2}。在黄色至棕褐色辐射的冰蒸发时,发现在室温下着色的固体膜粘附到反应容器的壁上。发现这些有机膜表现出可与烷烃、醛化物、醇和可能的烯烃以及取代的芳族官能团识别的IR带。这些光谱进行了比较与以前的研究紫外线或光子照射nonclathrated含烃冰。参考文献73篇。
Plasma-discharge irradiations were conducted for the methane clathrate expected in outer solar system satellites and cometary nuclei; also irradiated were ices prepared from other combinations of H{sub 2}O with CH{sub 4}, C{sub 2}H{sub 6}, or C{sub 2}H{sub 2}. Upon evaporation of the yellowish-to-tan irradiated ices, it is found that a colored solid film adheres to the walls of the reaction vessel at room temperature. These organic films are found to exhibit IR band identifiable with alkane, aldehide, alcohol, and perhaps alkene, as well as substituted aromatic functional groups. These spectra are compared with previous studies of UV- or photon-irradiated nonclathrated hydrocarbon-containing ices. 73 refs.
