摘　　要：利用LP-FTIR系统跟踪β-蒎烯和OH自由基的气相反应,研究了反应混合物随反应时间的变化情况,初步确定了反应中主要羰基产物诺蒎酮、甲醛、甲酸等随反应时间的生成情况,定性讨论了反应的可能机理,为进一步定量分析提供了基础.We tailed after the gas-phase reaction of β-pinene and OH radical using LP-FTIR. We studied the changing of the reacting mixture and determined the occurrence of the main carbonyl products as nopinone, formaldehyde and formic acid along with the reaction process. We made qualitative discussion of the possible mechanism of this reaction, and this could provide the base for further quantitative analysis.
