Determination of the state equation of NiX₂from the high-pressure spectra shifts

Abstract

The high-pressure state equation and alpha -P correlation of NiX2(X identical to F, Cl, Br, or I) are determined from the pressure spectra shifts of NiCl2 and NiBr2 based on the mu kappa alpha model. By using the state equation and alpha -P correlation the pressure behaviours of NiF2 and NiI2 are predicted.
