| Abstract: | Chemiluminescence associated with excimer states of XeO, KrO, ArO, XeS and XeSe has been generated through the reaction of electronically excited rare gas atoms, Rg(ns, 3P2, 3P1, or 1P1) with N2O, SCO, SCNH or SeCO. Branching ratios into the atom-transfer channels for reactions of Rg(3P2) are < 1%. Experiments using a superthermal reagent beam of Xe(3P2) indicate translational threshold behaviour for the reaction Xe(3P2) + N2O → (Xe+O−) + N2. Estimates of the initial vibrational population distributions and spectroscopic parameters of XeO and KrO have been achieved through a preliminary analysis of their chemiluminescence spectra. |
