Abstract : The transient molecule HBO has been studied by ab initio theoretical electronic structure techniques. The heat of formation of this molecule is predicted to be about-60 kcal/mole, more than 10 kcal/mole lower than previous estimates. This number is arrived at independently by fourth order perturbation theory calculations and by multireference c configuration interaction (MRCI) calculations both with a double-zeta plus polarization basis set. The activation barrier for the H + HBO hydrogen atom abstraction reactions is found to be about 20 kcal/mole and this reaction is predicted to be endothermic by about 8 kcal/mole.
