We report neutron diffraction measurements of liquid bromine at T = 298 K and T = 473 K and orthobaric densities. The structure factor, S(Q), in the range 0-8-15 A-1 and the non-bonded bromine atom-atom correlation function, g(r), are discussed and compared with previous results on Br 2 and Cl 2 . Monte Carlo (MC) computer simulations using the two-centre Lennard-Jones interaction model with idealized point quadrupole were performed at the higher temperature. This effective pair potential turns out to be unable to reproduce the Br 2 structure.
