We have used the second harmonic of a Nd: glass laser and a continuously tunable dye laser to measure the variation of the third-order nonlinear susceptibility |{^ (3) (-2₁+₂, ₁, ₁, -₂) |}^2 when ₁-₂ passes through the optical-phonon resonance in diamond. The frequency difference between the observed maximum and minimum determines the nonlinear electronic susceptibility ^ (3) E both in sign and magnitude with respect to the Raman susceptibility. A theoretical discussion of this interference is presented.
