揮發性分子在低溫固化下之能量作用機制研究II是一個延續性的研究計畫，主要是利用超高真空與低溫表面技術來模擬揮發性分子在固化下之結構與所對應的天文物理環境，並利用光譜、質譜等分析技術來監控固化之揮發性分子(冰晶)，分別在電子、真空紫外光子、超紫外光子與X光照射下之衍化過程，再經由液相與氣相層析等化學分析技術來分析能量照射衍化下所產生之殘餘物質之成份及其種類。本計畫欲執行的研究工作分為四項研究主題: (一)冥王星系統有機分子的生成機制研究，(二)天文物理冰晶的光脫附行為研究與光脫附量量測，(三)極性冰晶分子之自發性強電場研究，(四)X-rays引發之二次電子對簡單冰晶分子之衍化機制影響探討。期盼藉由這些研究結果能夠帶領我們對於星際物理與星際化學有更近一步的認知與了解。 ;This is a continual proposal and will use ultra-high vacuum and low temperature surface techniques to simulate condensed volatile molecules (interstellar ice analogs) in astrophysical environments in space, and use spectroscopy and mass spectrometry to monitor the evolution of ices irradiated by electron, vacuum-ultraviolet, extreme ultraviolet and X-ray, respectively. Moreover, The refractory residue will be analyzed by using a high performance liquid chromatography (HPLC) and a gas chromatography-mass spectrometry (GC-MS). The research topics of this proposal include (1) the formation mechanism of organic molecules in Pluto system, (2) the photodesorption yield and photodesorption mechanism of astrophysical ice analogs, (3) spontelectric field of polar ices, (4) the effect of X-ray induced secondary electron on the formation mechanism of products in ices. The results to be obtained from the proposed tasks will bring us understand more about the interstellar-physics and interstellar-chemistry.
