英文摘要	甲基过氧化氢(CH3OOH)是大气中一种主要的有机过氧化物,它的生成和去除过程将影响大气自由基的浓度水平。文章利用长光路傅里叶变换红外光谱(LP-FTIR)原位跟踪技术,实验室模拟研究了CH3OOH在常温和常压大气条件下的紫外光解反应,发现光解产物为HCHO,HC(O)OH,CH3OH,CO和CO2,此外实验中还观测到OH自由基的生成。根据分析结果推测了反应机理,并讨论了其大气化学意义。; Methyl hydroperoxide (CH3OOH) is one of the main organic peroxides in the atmosphere, and its formation and removal processes will have a significant impact on the concentration level of the atmospheric radicals. In the present paper, the technique of long path Fourier transform infrared (LP-FTIR) spectrometry was used for the in-situ investigation of the UV-photolysis of CH3 OOH under atmospheric conditions at normal temperature and pressure. The products of photolysis were identified as HCHO, HC(O)OH, CH3 OH, CO and CO2. Moreover, OH radicals were also detected. Finally, the mechanisms of this reaction were extrapolated on the basis of the analysis results, and the atmospheric implications were discussed.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000243417700017&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); EI; PubMed; 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 3; 12; 2222-2225; 26
