| 摘 要： | 本文报道了把多光子电离(MPI)方法用于气体反应动力学的研究.通过NO分子中间态O~2H的多光子电离作为对NO的检测方法,在流管体系中测得的NO与O_3反应速率常数为1.l×10~(-14)cm~3·mol~(-1)·s~(-1),与已报道的数据相符.在激光波长为365.45nm时,必须考虑NO~2光解产生的NO对MPI信号的贡献,在该波长时测得的NO_2的表观解离率为50%.

MPI technique for kinetic study of (NO+O3) reaction |
| |
| Abstract: | The kinetics of gas reaction by multiphoton ionization method is reported. The detection of NO is made by the resonant multiphoton ionization of NO via the C2H state. The rate constant of NO reaction with O3 is obtained to be 1.1 X 10-14cm3 mol-1s-1 in a flow system, in good agreement with previous data. It should be considered that the photodissociation of NO2 will also contribute to the MPI signal at 365.45nm. Apparent dissociation rate of about 50% at this wavelength has been obtained. |
