HO2 profiles in the thermal decomposition of H,02 in shock waves over the range 1000-1250 K were analyzed with respect to the reactions HO+HZOz+HOz+H20 (3) and HO+H0r~Hz0+02 (4). Reaction (3) shows a strong up-turn ofthe rate constant at temperatures near 800 K. Over the range 250-1250 K, k, can be

## Abstract This article describes an __ab initio__ investigation on the potential surfaces for one of the simplest hydrogen atom abstraction reactions, that is, HO + H~2~O β H~2~O + OH. In accord with the findings in the previously reported theoretical investigations, two types of the hydrogenβbon
