Abstract
The dissociation energy of the molecule ScO was determined: D0°(ScO) = 160.9±3.5 kcal/mole. The dissociation energies of the molecules YO and LaO, D0°(YO) = 168.6±2.8 and D0°(LaO) = 191.0±2.5 kcal/mole, are discussed. The molecules Sc2O, Y2O, Y2O2, La2O, and La2O2 were identified. Their atomization energies are: D0°(Sc2O) = 245±11, D0°(Y2O) = 258±8, D0°(Y2O2) = 445±12, D0°(La2O) = 266±8, D0°(La2O2) = 468±11 kcal/mole.Keywords
