The reaction of Hg(6 3P1)+H2, D2, and HD: Product rotational and vibrational distributions; isotope effects
摘要:
The initial vibrational and rotational state distributions of HgH and HgD products of Hg(6 3P1)+H2, D2, and HD have been determined. No isotope effect was observed for the vibrationless molecules or for HgH(v=1) but this effect appears for vibrationally excited HgD. The relative yields of the various reactions are reported for each vibrational level. In the reaction with HD, HgD is preferentially produced: [HgD]/[HgH]≂6.7.

Using FTIR spectroscopy, we have studied the insertion reaction of Hg excited in its 3P1 state in the HCl molecule in low-temperature Ar, Kr and N2 matrices. A new molecule HHgCl (DHgCl) is produced. In the rare-gas matrices, we also observe the formation of ClHCl− (ClDCl−) and some lines which may be tentatively assigned to HgH in very perturbed sites, although they are lying far from the known absorption
使用FTIR光谱,我们研究了在低温Ar,Kr和N 2基质中,以3 P 1状态激发的HG在HCl分子中的插入反应。产生了新的分子HHGCl(DHGCl)。在稀有气体矩阵,我们还观察ClHCl的形成- (ClDCl - ),并且可以被暂时分配给HGH在非常扰动位点的某些行,虽然它们是从在气相中已知的吸收躺在远。在Kr基体中,观察到Kr 2 H +的吸收光谱。该离子通过汞敏化反应获得。在氩气中,Ar 2 H +的产生量不明显。

The quenching cross-sections for collision of Hg(63P1) with H2 or D2 are measured in the temperature range 300
对Hg的碰撞(6淬火截面3 P 1用H)2或d 2是在温度范围300 <测定Ť <700 K.它们显示最低在Ť ≈400K,这表明这两个过程的发生,可以使用计算出的HgH 2势能曲线来解释。这些过程取决于入口通道。一种来自吸引人的3 B 2状态,它将以较低的相对速度起主导作用。另一方面,从所述斥力3 Σ +状态将控制在更高的动能。每个都提供HgH的形成和H 2激发或解离。如通过在光束中选择性激发HgH 2然后检测HgH所观察到的,它们分别对应于“快速”过程和“慢速”过程。

Atomic mercury subjected to mercury arc irradiation reacts in solid hydrogen to give the linear HgH2 molecule with strong IR absorptions at 1902 and 773 cm(-1). Annealing leads to HgH2 dimer and trimer, and warming above 7 K allows the hydrogen matrix to sublime and solid HgH2 to form. This covalent molecular solid is characterized by strong IR absorptions at 1802 and 673 cm(-1) and by decomposition at 150-170 K.

Initial rotational distributions of the vibrationless HgH or HgD molecules produced in the exoergic reactions of Hg (3P1) with H2, D2, and HD have been determined. No isotope effects have been observed. In the case of the reaction with HD the ratio [HgH(v″=0)]/[HgD (v″=0)] as well as the summed over all v″ ratio [HgH]/[HgD] have been measured.
