Nh. March et Mp. Tosi, COORDINATION-DEPENDENT EQUATION OF STATE OF EXPANDED LIQUID ALKALI-METALS AND CRITICAL-POINT PROPERTIES, Physics and chemistry of liquids, 29(3), 1995, pp. 197-199
To take account of the known structure of expanded heavy alkali metals
, a coordination number-dependent equation of stare is set up. It is t
hen shown that the critical constants T-c and V-c. are related by TcV1
/3 = constant, while the compressibility ratio is no longer constant t
hrough the alkali series, as required by experiment.
