The exact solutions of the D3(1) model (or the so(6) quantum spin chain) with either periodic or general integrable open boundary conditions are obtained by using the off-diagonal Bethe Ansatz. From the fusion, the complete operator product identities are obtained, which are sufficient to enable us to determine spectrum of the system. Eigenvalues of the fused transfer matrices are constructed by the T−Q relations for the periodic case and by the inhomogeneous T−Q one for the non-diagonal boundary reflection case. The present method can be generalized to deal with the Dn(1) model directly.
