Dissociation energy of a Sc2 molecule

Resumo

The–(G°(T)–H°(0))/T Gibbs energy functions have been calculated for Sc₂ at Т = 2000 K in the context of recent data on the low-lying electron states for this kind of molecules. In particular, some recent experimental results on the vapor composition over scandium are presented in this study. The data on the measured scandium vapor composition have been processed using the evaluated Gibbs energy function values. The advised dissociation energy value for Sc₂ is found to be D°₀(Sc₂) = 7750 ± 1750 cm^–1.
