Molecular orientational correlation in liquid halogens

摘要: The characteristic features of structure factor Sm(Q) liquid halogens F2, Cl2, Br2, and I2 have been discussed in terms preferred orientational correlations introduced between the nearest neighbors. estimated directly from experimental Sm(Q)’s these liquids are rather similar to each other related a ‘‘staggered parallel’’ orientation proposed previously for Br2. interpreted quite well by two structurally simple quantities, i.e., ratio intramolecular bond length intermolecular center–center separation correlated molecules l/Rc that effective diameter uncorrelated molecule l/σ. radial distribution functions also reproduced well.
