Abstract
We consider the interaction-round-a-face version of the nineteen-vertex model and derive a new quantum spin-1 chain. In the isotropic limit, the associated spin chain can be seen as three coupled Babujian-Taktahjan spin chains with different boundary twists. We compute the ground state short-distance correlation functions of the isotropic model in the thermodynamic limit by exploiting the shared integrable structure between the models.
