Abstract Nonlinear equilibrium fluctuation-dissipation relations are established for magnetic field-free binary ionic mixtures. These relations are derived from calculations of the second order partial current density response to perturbing fields which act on type A ions or on type B ions only. Our principal result connects asingle three-point dynamical structure function to a combination of quadratic partial density response functions. This kind of formulation makes it possible to obtain a more detailed description of three-point spectral correlations by evaluating the response functions from model-dependent kinetic equations. We carry out such an evaluation in the random phase approximation.
