X-ray scattering from diatomic molecules in the liquid state

A version of the Steele-Pecora equation suitable for use with diatomic molecules has been derived. Substitution of chlorine scattering factor coefficients and Percus-Yevick distribution functions into this equation led to the determination of total scattered intensity functions expressed as sums of gas scattering, spherical, and angular intensity contributions. The angular contributions were shown to be experimentally significant in the regions of the first and second peaks at high densities (ρ*≲ 1.2). Temperature was shown to have only a slight effect on total intensity. g000, g200, and g220 were found to be the principal contributors to the intensity.
