We study the linear problem associated with modified affine Toda field equation for the Langlands dual (g) over cap (boolean OR), where (g) over cap is an untwisted affine Lie algebra. The connection coefficients for the asymptotic solutions of the linear problem are found to correspond to the Q-functions for 9-type quantum integrable models. The psi-system for the solutions associated with the fundamental representations of g leads to Bethe ansatz equations associated with the affine Lie algebra (g) over cap. We also study the A(2r)((2)) affine Toda field equation in massless limit in detail and find its Bethe ansatz equations as well as T-Q relations. (C) 2015 Published by Elsevier B.V.
