摘 要
以193 nm之準分子雷射光解間質中之氯酸鉀（KClO3）後，由於低溫間質的晶格效應導致氯酸鉀的光解碎片（Photofragments）重新結合形成過氧亞氯酸鉀（KOOClO）。過氧亞氯酸鉀的吸收譜線位於1042.4、786.3、674.2、573.0 cm-1處。譜線的指認是根據37Cl同位素位移與類似化合物，KOONO，比較的結果。氯酸鈉（NaClO3）亦有類似的實驗結果，過氧亞氯酸鈉的吸收譜線位於1037.0、806.4 (801.1)、672.2 (666.2)、570.4 (568.9)cm-1處；在括號中的是因晶格效應而分裂的吸收譜線。

Abstract
Potassium chlorate (KClO3) isolated in solid Ar was irradiated with emission from an ArF excimer laser at 193 nm. Recombination of the photofragments led to formation of potassium peroxychlorite (KOOClO). Whereas KOOClO absorbs at 1042.4、786.3、674.2、573.0 cm-1. The assignments are based on observed 37Cl isotopic shift and comparison with similar compounds, KOONO. Similar results were obtained for sodium chlorate (NaClO3). Sodium peroxychlorite (NaOOClO) absorbs at 1037.0, 806.4, (801.1) 672.2, (666.6), 570.4, (568.9) cm-1; the numbers in parentheses are due to line splitting.
