摘要: 以激光磁共振为手段分别在紫外光照射和火花放电条件下观测了α-蒎烯、β-蒎烯与NO/NO2的化学反应.得到如下结果:α-蒎烯、β-蒎烯在火花放电条件下可与NO/NO2发生化学反应,α-蒎烯-NOx体系的反应比β-蒎烯-NOx体系的反应完全;α-蒎烯、β-蒎烯在紫外光照射下可与NOx发生不很剧烈的化变反应.所获得的信息对了解大气化学反应及光化学烟雾有着重要的意义.

Abstract: Reaction between NOx andα-pinene, β-pinene have been studied by LMR. Through determination of NO signals under ultra-violet light and spark discharge respectively, reaction between NO/NO2 and the above organic gas have been observed. α-pinene and β-pinene can react with NO/NO2 in spark discharge and more α-pinene reacted than β-pinene. Both α-pinen and β-pinene can react with NO/NO2 under ultra-violet light while not so acute. All of them are of great importance for understanding atmospheric chemical reaction and photochemical smog.

Key words: α-Pinene, β-Pinene, NO, NO2, LMR, Spark discharge, Ultra-violet light
