Experimental investigation of the chemistry of exccited states of rare gases. Fourth quarterly (and annual) progress report, July 15, 1978-October 15, 1978. [Reaction of Ar(/sup 3/P/sub 2/) or Xe(/sup 3/P/sub 2/) with XeO/sub 4/]

Description: A brief account is given of work on the quenching of XeF(B) and other excited rare-gas systems. A more detailed report is given of the studies of the vacuum uv photolysis of XeO/sub 4/ and reactions of Xe(/sup 3/P/sub 2/) and Ar(/sup 3/P/sub 2/) with XeO/sub 4/. (DLC)

Experimental investigation of the chemistry of excited states of rare gases. Annual technical progress report, October 15, 1976--October 14, 1977

Description: Tunable dye laser fluorescence has been combined with the flowing afterglow technique as a method for studying reactive intermediates present in the flowing afterglow. The radiative lifetimes and two-body quenching rate constants (with Ar carrier gas) for the Ar*(3p/sup 5/,4p) and Ar*(3p/sup 5/,5p) excited states were reported in the preceding year. During this year, we have measured the Ar* product states from the two-body quenching. More than 50% of the quenching leads directly to intermultip… more

Experimental investigation of the chemistry of excited states of rare gases. First quarterly progress report, 15 October 1978--15 January 1979. [Kr* + Cl/sub 2/]

Description: Analysis of XeF(B) and XeF(C) state quenching from photodissociation of XeF/sub 2/ was continued and progress was made on reactive quenching of the resonance states, Xe(/sup 3/P/sub 1/) and Kr(/sup 3/P/sub 1/). The study of the reactions of the resonance states of the rare gases was concentrated on the Kr* + Cl/sub 2/ reaction.

Experimental investigation of the chemistry of excited states of rare gases. First quarterly progress report, October 15, 1977--January 15, 1978

Description: The quenching of XeF(B) was studied using the steady-state photolysis of XeF/sub 2/ as the source of XeF(B). The product states from the sensitized reaction of Xe(/sup 3/P/sub 1/) with Cl/sub 2/ and COCl/sub 2/ also were studied. The new XeF(B) quenching rate constants are described. The pulsed laser induced fluorescence technique was used to measure radiative lifetimes and two-body quenching rate constant (with Ar) for the low energy Xe(6p)* states. Serious signal/noise problems for the lowest… more

Experimental investigation of the chemistry of excited states of rare gases. Second quarterly progress report, January 15, 1978--April 15, 1978

Description: Quenching of XeF(B) was studied using the steady-state photolysis of XeF/sub 2/ as the source of XeF(B). The XeF(C) state was observed, as well as the XeF(B) state, by using a very clean CO(A-X) resonance lamp to photolyze the XeF/sub 2/. Some of the preliminary data are discussed in this report. XeF(C) must be included in the kinetic scheme in order to understand the quenching of XeF*. The pulsed laser induced fluorescence technique was used to measure radiative lifetimes and two-body quenchin… more

Experimental investigation of the chemistry of excited states of rare gases. Third quarterly progress report, April 15, 1979-July 15, 1979

Description: Photosensitized studies of Xe(/sup 3/P/sub 1/) and Kr(/sup 3/P/sub 1/) reactions with fluorine, chlorine, bromine, and iodine donors have been very productive. Work on the laser excitation methods for generating selected states of the rare gas atoms lying above the np/sup 5/,n + 1s set of levels continued.
