title: Inter-molecular correlations in liquid Se2Br2.
abstract: The structure of molecular liquid Se2Br2 was analyzed by means of reverse Monte Carlo structural modeling, using a calculation based on high-energy x-ray diffraction data. It was found that, between the optical isomers of L and D types, the number of L-D neighboring molecular pairs increases, while that of the L-L and D-D pairs decreases with increasing temperature. From this temperature dependence and from the relaxation mode analysis of quasi-elastic neutron scattering spectra, it is reasonable to assume that the presence of L-D pairs relates to genuine inter-molecular interactions while the L-L and D-D pairs appear due to geometrical packing of the gauche-shaped molecules.
