The rate constants k,, k2 and t for the reactions of N( 'D) atoms with I-I>, HF, and 02, measured at room temperature in a discharge-flow atomic-resonance-absorption apparatus, have been determined to be (1.8 kO.8) x IO-'\*, (1.0\_+0.3) x lo-'" and (6.6 f 1.0) X lo-l2 cm3 s-l, respectively.

Rate coefficients, in units of 10-~0 cm 3 molecule-~ s-~, for the O(~D) reactions with H2, D 2 and HD at 298 K were determined to be 1.2 \_\_\_ 0.1, 1.1 + 0.1, and 1.2 + 0.1, respectively. The H atom yield in the O(~ D) + HD reaction, relative to that in the O(ID) + H 2 reaction, was measured to be
Mixtures of NO and NO/H2 in Ar were shock-heated and photolyzed with an ArF excimer laser. Measurements in these experiments of N-atom profiles using atomic resonance absorption spectrophotometry (ARAS) permitted the determination of two rate coefficients. The rate coefficient for the reaction (R1)
