Abstract
The temperature dependence of the liquid structure factor S(k) of dense monatomic fluids, and especially a variety of liquid metals, is studied by combining thermodynamics and fluctuation theory in the long wavelength limit k -> 0. Emphasis is placed on the connection of partial derivative S(0)/partial derivative T with thermal expansivity. Reference here is then made to recent semiempirical work of Lawson, who advocated an approximate relation, but at the melting temperature T-m, between [S(0)](Tm) and the Gruneisen constant.
