✦ Synopsis

Flash photolysis of CH3CHO and H2CO in the presence of NO has been investigated by the intracavity laser spectroscopy technique. The decay of HNO formed by the reaction HCO + NO * HNO + CO was studied a t NO pressures of 6.&380 torr. At low NO pressure HNO was found to decay by the reaction HNO + HNO 7 N20 + HzO. The rate constant of this reaction was determined to he kl = (1.5 f 0.8) X cm"/s. A t high NO pressure the reaction HNO + NOproducts was more important, and its rate constant was measured to he k:! = (5 f 1.5) X cm3/s. NO;? was detected as one of the products of this reaction.

Alternative mechanisms for this reaction are discussed.

## Abstract The mechanism for the reaction of HCO with HNO has been studied at the G2M level of theory, based on the geometric parameters optimized by the BH&HLYP/6‐311G(d, p) method. There are three direct hydrogen abstraction channels producing (1) H~2~CO + NO, (2) H~2~NO + CO, and (3) HNOH + CO
