摘要
飞秒化学是研究以飞秒 (1 0 -15s)作为时间尺度的超快化学反应过程的一门新兴学科。美国科学家 Zewail A H应用高性能染料激光器研究化学反应过渡态 ,实时地观察到了分子原子在反应中的瞬间变化过程 ,从而使化学反应机理由推测变为有确实证明的实际。飞秒化学的技术和方法为化学。
The femtochemistry is a new and developing subject with researching ultrashort chemical reaction (time scale 10 -15s). The American scientist Zewail A H has researched transitional condition on chemical reaction with using highperformance dyestuff laser machine, and observed on the spot instantaneous transformation of molecule and atom in chemical reaction. He made chemical reaction mechanism change to definitely true from speculation. The technology and method of femtochemistry provide expansive applicative prospect for researching in chemistry and biology field.
