The low temperature thermodynamics of the stable phase of vanadium has been assessed by the polynomial and Debye models from the experimental data available in literature. By means of the constrained nonlinear least squares curve fitting arithmetic, two sets of parameter values have been determined. Expressions of the thermodynamic functions C_p(T) and G(T)-H (298.15 K) at 0—298.15 K are presented. The low temperature thermodynamics of the metastable phase of vanadium can only be extrapolated by the Debye model. The expression of the thermodynamic function C_p(T) at 0—298.15 K is presented.
