研究了氯化碘的B3态(振动能级V'=12、16)的发散荧光光谱和碰撞电子淬火.借助激光诱地荧光(LIF)的方法,以氩离子激光器的502.3nm和514.5nm谱线做为泵浦源,并使用稳态近似处理得到了这两个态与气态ICl、H2O、CH2Cl2、CH3OH、C2H5OH、CH3NH2、C2H5NH2、CCl4和苯分子碰撞的电子淬灭速率常数和碰撞截面。我们探讨了分子间的相互作用,并且对比了ICl和IF的动力学模型。对于IF,偶极-偶极相互作用被成功地用于解释其碰撞电子淬灭机理。但是,本文证实:在ICI被其碰撞伴侣淬灭的过程中,碰撞对之间的偶极-偶极相互作用并非占主导地位。需要提出新的模型来解释这类碰撞。最后,我们简要讨论了使用ICl作为一种化学泵浦激光的介质的可能性.
The emission spectra and the collision electron quenching of the B3 state (V ’= 12, 16) of iodine iodide were studied. Using the laser-induced fluorescence (LIF) method, the 502.3nm and 514.5nm spectra of argon ion laser were used as the pump source, and the steady-state approximation was used to obtain the relationship between these two states and gaseous ICl, H2O, CH2Cl2 , CH3OH, C2H5OH, CH3NH2, C2H5NH2, CCl4 and benzene molecular collision electron quenching rate constant and collision cross section. We explored the intermolecular interactions and compared the kinetic models of IC1 and IF. For IF, the dipole-dipole interaction is successfully used to explain its collision electron quenching mechanism. However, this paper confirms that the dipole-dipole interaction between colliding pairs is not dominant during the ICI quench by its collision partner. A new model needs to be proposed to account for such collisions. Finally, we briefly discuss the possibility of using ICl as a medium for chemically pumped lasers.
