摘　　要：采用ns级瞬态吸收技术研究了液相CS2 HONO混合体系光解反应动力学.结果表明,在355nm紫外光作用下,CS2可与HONO光解产生的OH作用生成CS2OH,CS2OH会进一步与HONO作用生成CS2OH HONO这一中间产物,同时光谱分析表明体系中还生成了另外一种活性很强的加合物CS2NO+,这两种瞬态物种均未见报道.The ns grade transient absorption technique is used in the kinetics study of CS_(2)-HONO aqueous solutions. The results show that CS_(2) can react with OH radical from the 355 nm photolysis of HONO to form CS_(2)OH, which can react further with HONO to form CS_(2)OH-HONO, and spectrum analysis shows that there is still another reactive adduct CS_(2)NO^(+) formed in the solutions. Both of the two transient species have not been reported to the best of our knowledge.
