The atomization energies, AIf$ o. 110 i 5 kcal mole-' of the molecules AIAu, and ,II, Au have been determined as 121 k 6 nnd or 506.3 + 25.'1 and 4G0.2 + 20.9 kJ mole-', respectively. Theses atomization energies are discussed in terms of bond strengths and the Pauling model of a polar bond. .4vaila
The heat of formation of HO2 has been determined using highly accurate ab initio calculations. Our computed value is 3.5 +0.5 kcal/mol at 0 K (or 2.8kO.5 kcal/mol at 298 K). The accuracy of the current result is estimated on the basis of calibration calculations on Hz, OH, H,O, 02, and H202, which a
