✦ Synopsis

The high temperature kinetics of NH in the pyrolysis of isocyanic acid (HNCO) have been studied in reflected shock wave experiments. Time histories of the NH(X3Z-) radical were measured using a cw, narrow-linewidth laser absorption diagnostic at 336 nm. The second-order rate coefficients of the reactions: ( l a ) HNCO + Ar -NH(X'T) + CO + Ar (2) NH + NHproducts ( 3 ) NH + Ar-N + H + Ar were determined to be: k,, = 9.84 x l O I 5 exp(-43000/T, K) ( f = 0.65, F = 1.50) ( f = 0.7, F = 1.3) ( f = 0.5, F = 1.4) T

The kinetics of decomposition of azetidine {(CH 2 ) 3 N9 H)} was measured using single-pulse shock-tube techniques, over the temperature range in high argon 855-1100 K, dilution. These data confirm and extend an earlier investigation that utilized the very lowpressure pyrolysis method. A brief surve

NO 2 concentration profiles in shock-heated NO 2 /Ar mixtures were measured in the temperature range of 1350 -2100 K and pressures up to 380 atm using Ar Ο© laser absorption at 472.7 nm, IR emission at , and visible emission at 300 -600 nm. In the course of this study, the absorption coefficient of N
