    • d-like orbitals are included for pressures between 400 and 600 GPa, because of the increased d character of the valence electrons at compressed volumes. In the lower-pressure region, tests show that the inclusion of d basis functions gives rise only to changes within the uncertainties indicated.

    • Within the estimated uncertainties and over the range 0–600 GPa, the calculated dependence of pressure P on phonon frequency omega may be represented by a Birch-type expression P = 1.5 a (X7 - X5 ) [1- b (X2 - 1 )], where X = ( ω / ω0 )1/3 . The parameters are ω0 = 1341 cm-1_, a = 480 GPa, and b= 0.118.
