项目摘要
1. Adiabaticity of potential surface in photodissociation processesAtomic fragments produced in the photodissociation processes of molecules were detected with a laser multi-photon ionization technique and also with a laser-induced fluorescence technique. The non-adiabtic transitions between potential curves during the bnd break-up in the dissociation processes were investigated, which affect the electronic and translational states of the fragment atoms. The photodissociation processes of Cl_2, ICl, H_3O_2, SiH_4, Ethylene chlorides, and O_3 were studied.2. Adiabaticity of potential surfaces in reaction processesReactions of active atomic species, O(2P^<4\1>D), S(3P^<4\1>D), H(ls ^2S) and Xe(6p) with other molecules by collisions were investigated by observing the nascent translational and internal states of the reaction products. Since the photodissociation processes were used as sources of the active atom reactants and the products states were studied under single collision energies could be defined and angular distribution of the product velocities could be measured. The translational energies of the reaction products were calculated from the measured Doppler profiles. By measuring the fine structure branching ratios of product atoms and ro-vibronic states of product molecules, the adiabaticity of the potential curves in the reactions were investigated. The following reactions were studied, (1) O(^1D) + H_2, D_3 and HD, (2) O(^1D) + alkanes, (3) O(^1D) + CH_3OH, (4) SO(^1D) + H_2D_2 and HD, (5) S(^1D) + thiirane, (6) Ze(6p) + H_2 and HD, and (7) Xe(6p) + H_2O.
利用激光多光子电离技术和激光诱导荧光技术对分子光解过程中产生的原子碎片进行了探测。研究了解离过程中BND解离过程中势能曲线之间的非绝热跃迁对碎片原子电子态和平移态的影响。研究了Cl_2、ICL、H_3O_2、SiH_4、氯化乙烷和O_3的光解过程。研究了O(2P^<;4-1>;D)、S(3p^-lt;4-1>;D)、H(ls^2S)和Xe(6p)等活性原子物种与其它分子的碰撞反应。由于光解过程被用作活性原子反应物的来源,并且在单次碰撞下研究了产物的状态,因此可以定义能量并测量产物速度的角分布。根据测量的多普勒谱计算了反应产物的平动能。通过测量产物原子的精细结构分支比和产物分子的非振动态,研究了反应势能曲线的绝热性。(1)O(^1D)+H_2,D_3与HD,(2)O(^1D)+烷烃,(3)O(^1D)+CH_3OH,(4)SO(^1D)+H_2D_2与HD,(5)S(^1D)+硫烷,(6)Ze(6p)+H_2与HD,(7)Xe(6p)+H_2O。
