Abstract : Summaries are presented on work already published in the literature. These include kinetics of atom and excited molecule reactions, and recombinations; absolute quantum yield measurements; and diffusion coefficients. The following summarizes work yet to be published. The reaction of O atoms with aluminum vapor was found to produce chemiluminescent glows which consisted of a continuum, whose intensity distribution was similar to that obtained from rocket experiments. The reaction of O atoms with trimethyl aluminum (TMA) also produced a chemiluminescent continuum. No resonance radiation corresponding to A10 emission could be produced by irradiating the reaction products with continuum or discrete light sources. The reactions of a number of metalorganic compounds with active nitrogen produced glows which consisted of a number of bands, some of which have not yet been identified as well as lines from excited metal atoms. The rate of reaction of TMA with molecular oxygen was studied using the mass spectrometric technique. The rate constant was found to be (2 = 0.3) x 10 to the minus 16th power cc/molecule sec. The rate of the reaction of TMA with atomic oxygen was found to be greater than could be measured with this technique and must therefore occur at close to collision frequency. (Author)
