长期以来,化学家渴望着能观测到化学反应中寿命仅微微秒(10~(-12)秒)的瞬息即逝的中间产物的分子构型。闪光光解的建立和发展,脉冲辐解技术的突破,已使这种愿望变成了现实。现在,在国外,这种测定技术正在对现代化学的微观、动态研究发挥着重大作用。瞬态产物测定原理光化学反应和辐射化学反应,很少由反应物直接形成最终产物,大都生成多种短寿命(10~(-6)~10~(-12)秒)的瞬态粒子(不稳定的中间产物),经过相当复杂的变化过程,才过渡到最终产物。因为各个中间步骤进行得很快,常规分析方法无济于事。人们后来也曾应用
For a long time, chemists were keen to observe the molecular configuration of transient intermediates with only a few seconds of life (10 to -12 seconds) in chemical reactions. The establishment and development of flash photolysis and the breakthrough of pulsed radiolysis technology have made this desire a reality. Now, abroad, this measurement technique is playing a significant role in the micro and dynamic study of modern chemistry. Transient Product Determination Principle Photochemical reactions and radiation chemical reactions, the formation of the final product is rarely formed directly from the reactants, most of the generation of a variety of short-lived (10 -6 (10-12 seconds) transient particles (not Stable intermediate), after a very complex process of change, before the transition to the final product. Because of the intermediate steps, routine analysis is of no avail. People have also applied later
