  Vibrational energy and bimolecular reactions: Enhancement of the electron transfer derived product channels for quenching of Xe(³P₂) and Kr(³P₂) atoms by CF_nCl_4−n, C₂F_nCl_6−n, and CF₃CFClCF₂Cl

  摘要：

  The yields of XeCl(B,C) and KrCl(B,C) from the reactions of Xe(3P2) and Kr(3P2) metastable atoms with chlorofluoromethanes and chlorofluoroethanes are enhanced by the addition of vibrational energy to the molecule. The reactions were studied in a fast flow reactor with He or Ar carrier gas; vibrational energy was added to the molecules by multiphoton absorption from a CO2 laser pulse at fluences of 0.2–1.0 J cm−2. The enhancement of the XeCl(B,C) or KrCl(B,C) product was observed by monitoring the B–X fluorescence intensity in real time following excitations by the CO2 laser. Enhancement factors are reported for reactions with CF2Cl2, CFCl3, CF3CFCl2, CF2ClCF2Cl, CF2ClCFCl2, and CF3CFClCF2Cl; survey experiments are presented to demonstrate enhancement of XeCl* and XeBr* from vibrationally excited CF2BrCl and CF3CH2Br. The decay times of the XeCl(B) and KrCl(B) signals provide information about the relaxation rates of the vibrationally excited CFnCl4−n and C2FnCl6−n molecules. In order to have a reliable reference, the total quenching rate constants and the branching fractions for XeCl(B,C) and KrCl(B,C) formation for 300 K conditions also were measured for most of the compounds; the branching fraction for XeCl* formation form CF3CCl3 is large for a polyatomic molecule.

• Emission spectra of KrXeCl*, KrXeBr*, KrXeI*, ArKrF*, and ArKrCl*

  Sensitized reactions of Xe and Kr with halogen donors in the presence of high buffer gas pressures of Kr and Ar, respectively, have led to the observation of five emission bands in the ultraviolet region of the spectrum. These broad structureless bands are assigned to the mixed rare gas–halide trimers KrXeCl, KrXeBr, KrXeI, ArKrF, and ArKrCl. Despite an extensive search, no emission corresponding to KrXeF could be found and this mixed trimer may be unstable because of interaction with a lower repulsive state. The positions and half-widths of the five emission bands are characterized, and the formation mechanism of the mixed trimers in these experiments is discussed.

  The ArCl(C–A), KrCl(B–X,C–A,D–X), and XeCl(B–X,C–A,D–X) emissions have been observed from ionic-recombination reactions of Rg+ (Rg=Ar, Kr, or Xe) with Cl− in the flowing afterglow. Positive Rg+ ions are formed by He(23S)/Rg Penning ionization, while negative Cl− ions are produced through thermal electron attachment to CCl4. The dependence of RgCl* emission intensities on the buffer He gas pressure indicates that the excimer emissions arise from three-body reactions of Rg++Cl− +He. The spin–orbit state selectivity in the KrCl* and XeCl* formation is studied by isolating one of the spin–orbit levels of Rg+,2P1/2 or 2P3/2 . Although the Kr+(2P1/2) reaction provides the KrCl(B–X,C–A,D–X) emissions with B:C:D distribution of 0.19±0.02:0.12±0.01:0.69±0.04, only XeCl(D–X) emission is observed from the Xe+(2P1/2) reaction. The Kr+(2P3/2) and Xe+(2P3/2) reactions give the RgCl(B–X,C–A) emissions with B:C branching ratios of 0.60±0.06:0.40±0.04 for KrCl* and 0.62±0.06:0.38±0.04 for XeCl*. The high propensities for the D formation from the Rg+(2P1/2) reactions and for the B and C formation from the Rg+(2P3/2) reactions suggest that Rg+(2P1/2)+Cl− and Rg+(2P3/2)+Cl− characters are conserved well for the formation of RgCl* in the three-body ionic-recombination reactions. The relative formation rate of RgCl(D) from the Rg+(2P1/2) reaction to that of RgCl(B,C) from the Rg+(2P3/2) reaction was estimated to be 0.14±0.02 for KrCl* and 0.033±0.006 for XeCl*. The slower RgCl(D) formation rates are attributed to fast predissociation of [Rg+(2P1/2)Cl−]* intermediates into Rg*+Cl and/or Rg+Cl* than that of [Rg+(2P3/2)Cl−]* ones.

  Three-body ionic-recombination reactions of Rg++Cl−+He (Rg=Kr or Xe) leading to RgCl* excimers and their predissociation products (Rg* and Cl*) have been studied by observing emission spectra in the flowing afterglow. The branching ratios of KrCl(B,C,D):Kr(5s 3P1):Cl(4p) are 0.13:0.014:0.86 in the Kr+(2P1/2) reaction, while those of KrCl(B,C):Kr(5s 3P1):Cl(4s) are 0.64:0.23:0.13 in the Kr+(2P3/2) reaction. Although the Xe+(2P1/2) reaction gives only XeCl(D), the Xe+(2P3/2) reaction provides XeCl(B,C) and Xe(3P1) with branching ratios of 0.98:0.02, respectively. The preferential formation of the Rg(3P1) level by the Rg+(2P3/2) reaction can be explained as being due to the conservation of ion configuration with J=3/2. The electronic state distribution of Cl(4p) in the Kr+(2P1/2) reaction is nonstatistical providing any preference for doublet, quartet, or for particular J states, while the J=3/2 levels of Cl(4s) are favored channels relative to the J=1/2 and 5/2 ones in the Kr+(2P3/2) reaction. It is predicted that the dominant predissociation product in the Xe+(2P1/2) reaction is the metastable Xe(3P0) atom.
