ResumoA set of Kramers-Kronig relations are obtained for the second-harmonic generation susceptibility ${\mathrm{\ensuremath{\chi}}}^{(2)}$(\ensuremath{\omega},\ensuremath{\omega}). Together with the asymptotic behavior in the frequency variable they give a set of sum rules up to the fifth moment of the susceptibility.
