摘要
光解含有微量的H2O存在的O3/Ar間質後，觀測到位於804.3 cm-1和903.3 cm-1新的紅外吸收譜線，並分別被認為屬於O3-和Ar2H+的振動吸收。所觀測到Ar2H+和O3-的 3振動模之波數與前人之類似實驗結果一致。另外，O3-的 3振動波數較O3之 3小。由18O光譜資料顯示，我們推測O3-具有C2v對稱結構。同時，我們也討論了可能的形成機制。

Abstract
After irradiation of O3/Ar matrix in the presence of trace H2O with 121.6 nm, new IR absorption lines at 804.3 cm-1 and 903.3 cm-1 were observed and ascribable to O3- and Ar2H+, respectively. Observed wavenumbers of Ar2H+ and the 3 mode of O3- are consistent with previous similar report. In addition, the 3 mode of O3- is smaller than that of O3. We derived O3- with C2 symmetry on the base of observed 18O-enriched spectra information. Possible mechanisms of formation are also discussed.
