Vaporization of Compounds and Alloys at High Temperatures. Part 9 - Correlation of Dissociation Energies of Gaseous Molecules and of Heats of Vaporization of Solids; Homonuclear Diatomic Molecules

Abstract

Homonuclear diatomic molecules are classified according to the ratio alpha = (heat of vaporization of an atom/dissociation energy of the diatomic molecule). For transition elements the heat of vaporization of an atom can be represented by a-b (e), where e is the excitation energy of the free atom to a set of electronic levels; a and b are empirical parameters. Experimental conditions for observing unknown homonuclear diatomic molecules of transition elements are estimated for alpha = 2 and 5, using a calculated self-consistent set of free energy functions.
