Abstract: Lin proposed earlier based on qualitative considerations that electronic motion was associated with negative absolute temperature. Here, a local temperature formula is proposed for electronic motion in atoms and molecules, which allows the existence of negative absolute temperature in a local sense in thermodynamic equilibrium. The proposed temperature formula is a function of total energy density ε(r), entropy density s(r) and electron density ρ(r).
Keywords: negative absolute temperature; local temperature; entropy density; energy density; electron density
