We calculate the correlation function for fluctuations of the electrical component of a light field which is scattered by fluctuations in the orientation of the molecules in a nematic liquid crystal (NLC). It is shown that taking into account the fluctuations of the complete orientation tensor Sij leads to the occurrence of elements in the correlation matrix of the scattered field which cannot be obtained from examining the scattering of light from the director fluctuations in an NLC. We compare the correlation matrices of the fluctuations of the scattered field in an NLC and an isotropic liquid crystal (ILC). It is established that the correlation matrix of the scattered field changes strongly on transition from scattering light in the isotropic phase of the LC to scattering in the nematic phase.
