Size and Pressure Effect on Ols Energy

The pressure and size coupling effect on the Ols-level shift follows the currently proposed mechanism. Molecular coordination reduction and pressure increase have the opposite effect on the H-O bond length and energy that determines the core-level shift. Therefore, coordination reduction effects the same to heating, growing size enhances the effect of pressure, on the phonon relaxation dynamics and binding energy entrapment. 

Systematic studies [8, 9] also revealed that cooling enhances the effect of compression on the structure phase transition and dipole moment of ice.
