“…(2), (6)-(S), (17), and (19) for which either measured values or estimates derived from measurements of similar reactions involving other rare gases were used. The reactions of Table I1 are not important enough, relative to those in Table I, to affect our kinetic model of the behavior of rare-gas mixtures when eliminated by 123.6-nm radiation.…”

The formation and destruction of excited rare-gas dimers have been studied using resonance optical excitation of high-pressure gas mixtures containing Kr. From an analysis of the resulting emission, 19 reaction rate coefficients have been inferred. It is concluded that atom-atom interchange processes play a major role in rare-gas eximer formation, and that stepwise relaxation down the eximer vibrational ladder is less important than multistep relaxation due to atom-atom exchange in the excited eximer.Of the 29 reactions listed in Table I and the 23 reactions listed in Table I1 which could occur in mixtures of Kr with Ar or He, reactions (l), (3) + (4), and (18) have been measured by Turner [32] (as 1.3 X and 7.6 X in s-l, cm3/s, and cm6/s, as appropriate), while Hughes' has measured ky, kq, and k17 (5.3 X lo6, 5.5 X This paper describes spectroscopic measurements on mixtures of Kr and other gases when this mixture is excited by the 123.6-nm resonance line of Kr from an optically thick source. These measurements are interpreted to give the reaction rates of reactions (relative to the reaction rates of reactions Hughes [31] has measured k7 to be 5.3 X lo6 sl, k3 + kq = 5.5 X lo-?' , and h17 = 1.75 X 108. 4 X 1.8 X lo8).

Light emission in the ultraviolet region is observed from gaseous mixtures of xenon and iodine using the pulse radiolysis technique with subnanosecond time resolution. Emission maxima at about 253 and 319 nm are ascribed to XeI*(2S1/2), and kinetic evidence is presented which supports the conclusion that Xel* is formed by reaction of ground state Xe with excited molecular iodine. Evidence is also presented which indicates that the same species is formed by a sequence of ionic reactions. An emission band due to excited I2, with a maximum at 342 nm, is also observed. Three distinct reaction sequences, one of which involves ions, are involved in producing the excited I2.

“…The lasing transitions were labeled BX and were quickly understood as charge-transfer transitions from a bound ion-pair excited state to the essentially unbound ground state . This picture (see Figure ) was corroborated by more detailed theoretical computations. − Yet XeF was unique among the RgX species, in that its emission spectrum at high pressures exhibited rich fine structure that could not possibly arise from the bound-free transitions expected. , To the contrary, the X state had to be bound by much more than predicted for only van der Waals attractive forces . Not surprisingly, XeF became the focus of much attention by molecular spectroscopists.…”

The B ( 1 / 2 ) and C ( 3 / 2 ) ion-pair excited states of XeF are coupled by the rotational Hamiltonian, producing perturbations in the rotational structure of B f X( 2 Σ + ) transitions involving υ′ levels <5. Five υ′ -υ′′ bands in the B f X emission spectrum of the single isotopomer 136 Xe 19 F are analyzed by a deperturbation model to yield improved spectroscopic parameters (cm -1 ) for the low-υ regions of the B and C states: For B, ω e ) 308.09, ω e x e ) 1.480, B e ) 0.145 29, and R e ) 0.000 675; for C, ω e ) 345.1, ω e x e ) 2.10, B e ) 0.165 42, and R e ) 0.001 48. The C state lies 797 cm -1 below the B state, with R e ) 2.473 Å. The electronic perturbative coupling element for B-C interactions is 1.632, which is 6% below the simple Hund's case c-based prediction ( 3) and just 3% greater than an estimate obtained from a more elaborate case a approach. † Part of the special issue "Donald Setser Festschrift".
