Different theoretical approaches in determining heats of formation (AHf) at the chemical accuracy level ( +\_ kcal/mol) are commented on. We show that calculations at the MP4SDTQ/6-311 + + G (3df, 2p) level of molecular orbital theory reproduce experimental results best. Accurate determination of AH

โฆ Synopsis
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 are also discussed in this work.

The importance of the quadratic configuration interaction (QCISD( T) ) step in Gaussian-2 (G2) theory is investigated for 125 test cases. The average deviation with experiment increases from 1.21 to 1.91 kcal/mol when this step is not included in G2
We investigate the effect of neglecting the basis set superposition error in the theoretical determination of A& We show that this error is, in fact, larger than the claimed accuracy of recent computations of theoretical heats of formation. We further demonstrate that neglecting the basis set superp
The kinetics of the oxidation of hydrogen iodide (HI + 0 2 ) a t low temperature (414-499 K) in the gas phase by the method of idination kinetics is complicated by a heterogeneous reaction between hydrogen iodide and oxygen. Present work leads to an upper limit for the bimolecular rate constant kl f
A new set of MNDO parameters is obtained by fitting reference data from small carbon clusters and experimental data for &I. This set of parameters was applied to a series of fullerenes, ranging from Cl0 to GO, and yielded good results for geometries and heats of formation; for example, the estimated
Using currently available thermochemical and kinetic data and estimation methods to analyze the thermochemistry and the kinetic parameters of the elementary reactions involved in the oxidation of HCl and HBr, reaction mechanisms are proposed which account for the previously reported reaction product
