• Exact results are derived, via the Temperley-Lieb-Jones algebra, for the ground state energy per site, surface energy, gap and central charge of the anisotropic generalization of the spin-1 biquadratic model. A recently observed simplification in the ground state energy of the U_q[SU(2)]-invariant Zamolodchikov-Fateev model at q=e^<iπ/4> is shown to be a direct consequence of a trivial representation of the related operator algebra. Similar points are conjectured to exist in the more general U_q[SU(2)]-invariant spin-S chains at q=e^<iπ/(2+2s)>.
