碩士 === 國立中央大學 === 機械工程研究所 === 97 === Our planetary system is composed of the collapse of dense molecular cloud, and it is attracted each other by gravity. The collapse of dense molecular cloud are composed of gases and sub-micrometer sized grains. The main composition of the interstellar solid material include H2O、 CO、CO2、CH3OH、CH4、OCN-、and NH2COOH etc,. These interstellar ice after the energetic particle bombarded that are being come from the solar wind and how evolves its interstellar ice is the main place where we probe into. In our experiment is to utilize cryogenic technique(24 K) and ultra high vacuum(6×10-10) to simulate the environment of outer space, it use H3+ ion to bombard the ice that include NH or OH bond chemical compound and H2O mixed, and the energy as 15keV. It used FTIR to scan the frozen and infrared spectrum of the ice crystal. Finally, analyze the quantity of the CO(2138cm-1)、CO2(2341cm-1) and OCN-(2165cm-1) bond that produced, and analyze the influence of mixing and proportion of H2O with NH and OH bond.
