摘要 銀河系中大約存在15%可見物質，這些物質是由氣體(99%)與微小晶粒(1%)所組成，而在太空環境下，溫度的分布大約介於10K至100K之間，在如此低溫下許多氣體將會附著於星際微小晶粒的表面上，因而形成星際冰晶。而太空中冰成分主要包含H2O、NH3、CH3OH、CH4、CO及CO2……等經由高能粒子輻射後這些冰會產生有機複合化合物。 本實驗選擇15keV的H3+離子撞擊含CH鍵或CO鍵的化合物(CH3OH、CH4、CO及CO2) 與H2O或D2O混合之冰晶做研究分析，由實驗後發現在每個冰晶樣品的傅立葉轉換後紅外光譜圖上皆有CO(2136 cm-1)和CO2 (2339 cm-1)，為了了解在各個冰晶樣品對於CO(2136 cm-1)和CO2 (2339 cm-1)面積產量在不同混合比例(1:1、1:3)、和不同混入溶液(有同位素元素的H2O與D2O)下的生成關係，以及全冰晶樣本中在CO(2136 cm-1)與CO2 (2339 cm-1)總生成面積產量比較，故作此分析。 ABSTRACT It has about 15% visible matter in the galaxy, and this visible matter is composed of 99% gas and 1% sub-micrometersized grains. In outer space environment, the temperature range is between 10K and 100K.In the low temperature environment, gases form into ice on the grains. The interstellar ice is composed primarily of H2O、NH3、CH3OH、CH4、CO and CO2, etc. The complex organic compounds can be created in the ice via irradiation process. We use 15keV H3+ bombard CO- or CH- compounds with H2O and D2O ice mixtures. After H3+ bombard CO- or CH- compounds with H2O and D2O ice mixtures. We observe CO(2136 cm-1)and CO2 (2339 cm-1) on all FTIR spectra. In order to compare CO(2136 cm-1)and CO2 (2339 cm-1) production yield, we use different mixture proportion (1:1、1:3),mixture solution (H2O、D2O) and ice sample. Therefore, this thesis does analysis.
