Holes and Cells in Liquids

Abstract

A certain amount of exact information about cells and holes in liquids can be deduced from the radial distribution function. For example, for cells small enough so that they cannot contain more than one molecule, we can find the radial distribution function around an occupied cell or around a hole (empty cell), the probability that a cell near a molecule will be occupied, and the probabilities for occupancy or nonoccupancy of pairs of cells near each other. Also, the probability that a cell of arbitrary size will be empty can be calculated. Examples are given using an experimental radial distribution function for liquid argon.
