【摘要】 <正> 目前对于红外激光诱导的异构化研究甚少,有关烯丙醇分子的激光化学反应尚未见报道,本文报道了烯丙醇分子红外激光诱发的1,3-σ迁移反应及离解反应。 1 实验方法 以光栅选频TEA CO₂ B型脉冲激光器为激发光源,脉宽<150 ns,脉冲重复频率1 Hz,光束聚焦至反应池中央,焦斑面积<0.1 cm².反应池先抽至0.13 Pa以下,再充入一定压力的烯丙醇和缓冲气体Ar或N₂,用Perking-Elmer 983型红外分光光度计和MAT 454型色质联更多还原

【Abstract】 The infrared laser induced chemical reaction of allyl alcohol is a multiple pathway reaction with the competition between dissociation and isomerization. The isorrierization proceeds via 1,3-hy-drogen sigmatropic shift in an excited electronic state, principally agreeing with the classical photo-chemically allowed Woodward-Hoffman rule.更多还原
