Abstract
The theory of the dispersion of the refractive‐index anisotropy induced in nonpolar fluids by external electric fields is extended to the case of chemically reacting fluids. Explicit expressions for the induced anisotropy are derived for a model nonpolar fluid with (1) no pair correlations, (2) rotational diffusion dynamics, and (3) a simple two‐state (or species) chemical equilibrium. Limiting cases of the results are discussed.
