Thermodynamic functions and formation enthalpies of scandium trihalides molecules

Abstract

A critical analysis of experimental and theoretical data on the structure and vibration frequencies of scandium trihalides molecules is performed. The values of molecular constants are chosen, and the thermodynamic functions are calculated in the temperature range T = 298.15–6000 K. The obtained values are introduced into the database of the IVTANTERMO software package. The sublimation enthalpies are found, and the enthalpies of formation of gaseous scandium trihalides are calculated.
