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.

The rate of reaction of O(lD2) with X20 relative to that of reaction with neopentane has been determined by a competitive method. The value obtained, kI.&&op\_ = 0.38, is in good agreement with that determined previously\_ in this laboratory. by a different experimental technique. It is aiso fomd th
The O(3P) + CION reaction has been studicd in a fast flow system over the temperature range from 213 to 295 K, using the air-aftereIow technique for the detection of oxygen atoms under pseudo first order conditions.
