Investigation of the neighborship properties of several monatomic liquids

The neighborship properties of several monatomic liquids are investigated. This builds upon indirect methods (numerical techniques) explored in experi ments with 2D foams (Graham et al., J. Phys. Chem. B 1997, 101, 11211). In the foundation study, the methods were applied to the radial distribution f unction G(r) for foams and liquid sodium. Further development is presented here so as to widen the method applicability and to learn more about neighb orship distributions. The method is demonstrated using G(r) for hard sphere s; favorable comparisons are found between the distributions so obtained an d via the theory of Mazur (J. Chem. Phys. 1992, 97, 9276). Using published G(r) data, application is made to a diverse set of monatomics: lithium, pot assium, argon, indium, gallium, and mercury. Overall, this research offers structure comparisons among different liquids and identifies neighborship t rends. In addition, a simple way to partition G(r) is further established w hich requires no specification of the interaction potentials.
