The goal of this work is to provide accurate chemical kinetic information on individual reactions for use in Army propellant combustion models. A critical review was prepared, discussing the best data for a number of dark zone species reactions. The effect of the rate coefficients, and their temperature dependence, on the models is described. Experimental and theoretical studies of NH reactions have been made. It is shown that HNO can not be a product of its reactions with CO2 and H2O. If it were, nitrate ester combustion would not show dark zones, contrary to the observations. For the NH H2 reaction k833-1432 K was measured to be 3.5 x 10 -11exp-7758 KT cm3molecule-1s-1.
