“…is chemical in nature is well established (Lin & Kaufman, 1971;Dodge & Heicklen, 1971;Black et al, 1969Black et al, , 1975. The predominant reaction pathway appears to be to ground state products with a small contribution (0.3 %) in the channel producing NO(B2Il) (Slanger et aI., 1971;Herbelin & Cohen, 1973). The latter is formed in preference to NO(A 2E+) (Welge, 1966).…”

An extensive evaluation is presented of the available gas phase chemical kinetic rate constants for the interac· tions of the low lying electronic states of several atoms and molecules with numerous collision partners. These include the following excited states: C(2 1 D 2 ,2 1 S o ), N(2 2 D31l,5/2, 2 2 P1I1, 3/2), P(32D3/2,51l,32Pl/2,3/2), S(3 1 D 2 ,3 I S 0 ), Se(4 S P o ' 4 1 D 2 ,4 1 S 0 ), Te(53PI,o,51D2,5ISo)' COCa an, a'3I;+,d aA,e 3I;-,A III), CS(a all, A III), OH(A 2I;+), OD(A 2£+), 02(C lE~,C 3A u .A 3I;~,B 3r;~), and S2(a IAg,b lE;,A ar;~,B ar;~). Wherever possible, recommended values are suggested. Much of the data refers only to room temperature. To facilitate the evaluation, colJision·free radiative lifetimes often have been required. These also have been evaluated and are presented. The mechanisms of the interactions and the various potential kinetic channels are discussed. These include such processes as chemical reactions, electronic quenching to the ground electronic state, electronic cross relaxation to an adjacent excited state, and for molecules, vibrational and rotational relaxation processes within the excited state. A complete coverage of the literature published prior to 1978 has been attempted.

A numerical code has been developed to simulate the characteristics of HF chemical laser based on non-chain reaction pumped by a planar sliding discharge radiation. The model considers transport of VUV pump radiation through the nonlinear absorptive active medium containing NF3IH2IN2/Ar gas mixture coupled with chemical and lasing kinetics describing the temporal and spatial evolution of particle species concentration and intracavity lasing photons density. The relative importance of various kinetic processes is evaluated and a 3 .2 J/I laser output specific energy is calculated along the laser axis.
