Rate constants for argon fluoride (ArF*) formation from reactions of argon(3P2,0) with fluorine-containing molecules and the pressure dependence of the C to B state ratios for argon fluoride (ArF*) krypton fluoride (KrF*), and xenon fluoride (XeF*)

Abstract

The change in the R dependence of T. at ca. 8R is not apparent when T" Is plotted as a function of mole percent salt. Indeed for R > 4, T" Is a linear function of mole percent salt for the Ca(N03)2 system (Figure 4, Inset).10

Dynamics of Excited Rare-Gas Atoms with Halide Molecules: The Ar(3P) + ClF → ArCl* + F, ArF* + Cl Reaction

“…Instead, Liegel et al 26 deduced from experiments an opposite ordering. Furthermore, the experimental rate constants referred to in the present work 37 do not distinguish among the B and C states, since it is provided a unique, global rate constant value. Given this uncertainty and the small energy gap between both B and C states, in the present work it has been chosen to label the ArX* states as 2 Π, since it is the excited state actually picked from our calculations (the noncollinear asymptotes leading to an electron in a perpendicular π orbital).…”

“…Most of the above experiments have been performed on homonuclear diatomic halogen molecules, 1,3, information concerning the heteronuclear variant being less frequent. 6,17,[36][37][38] However, as will be seen below, this latter case allows for the possibility of analyzing excimer formation within competing mechanisms, thus providing, in principle, a more complex reactive process.…”

“…One would then expect a reaction scattering dynamics showing up fingerprints from the above features. The experimental thermal rate constants for both channels are known, 37 which will be used as a reference to check the reliability of the present study.…”

“…Bulk experiments were performed by Setser et al., − who derived, from flowing-afterglow studies, the spectroscopic properties, the disposal of available energy into product vibration and the thermal rate constants, for reactions between metastable rare gas atoms and halide molecules (of the type MX, X 2 , and XY, where M = CH 3 , ... and X,Y = F, Cl, Br, ...). Most of the above experiments have been performed on homonuclear diatomic halogen molecules, ,,− information concerning the heteronuclear variant being less frequent. ,,− However, as will be seen below, this latter case allows for the possibility of analyzing excimer formation within competing mechanisms, thus providing, in principle, a more complex reactive process.…”

Noble Gas Bonding Interactions Involving Xenon Oxides and Fluorides

“…In the late 1970s, gas phase Ng halides and oxides motivated active interest for their application in the UV laser action and for the characterization of their role in many other gas-phase elementary processes [ 69 , 70 , 71 , 72 ]. Moreover, the investigation of the nature of involved interactions has been also an important target of the basic research [ 73 , 74 , 75 , 76 , 77 ].…”
