Liquid structure is described by the pair‐correlation function. If the liquied particles are molecules then the respective correlation function depends on distance and several angular variables; hence, for the sake of simplicity a symmetry‐adapted representation must be used. The most important structural parameters of this molecular pair‐correlation function can be determined approximately by a combination of several scattering experiments, such as neutron (employing different isotopes), X‐ray and electron diffraction. Light scattering, dielectric, and nuclear magnetic relaxation experiments provide further, albeit less direct, access to such determinations. Some results obtained by measurements on chloroform are reported. Theoretical computations of these structural parameters are also discussed.
