Thermodynamic functions of germanium oxide molecules in the gaseous phase: GeO2(g), Ge2O2(g), and Ge3O3(g)

Abstract

Critical analysis of experimental and theoretical data on the structure and vibrational frequencies of GeO₂, Ge₂O₂, and Ge₃O₃ molecules is performed. The values of molecular constants are chosen, and thermodynamic functions in the rigid rotator–harmonic oscillator approximation are calculated in temperature interval Т = 298.15–3000 K. The values obtained are introduced into the data base of the IVTANTERMO program complex.
