Abstract: We use Freud equations to obtain the main term in the asymptotic expansion of the recurrence coefficients associated with orthonormal polynomials $p_n(w^2)$ for weights $w=W\exp(-Q)$ on the real line where $Q$ is an even polynomial of fixed degree with nonnegative coefficients or where $Q(x) =\exp(x^{2m}),\, m\geq 1$. Here $W(x)=\vert x\vert^{\rho}$ for some real $\rho>-1$.
