A trigonometric function parametrization of Yang-Baxter (Y-B) relations is de-scribed in terms of n -j symbols of su.(2), a deformation of su(2). The formalismstarts with deduction of the Y-B relation for the [RF (interaction round a face) modelof su.(2) from a general operator relation for the vertex model. The relation obtainedfor the IRF model is transformed into the Y-B relation for the vertex model using theproperty that the 3 -j symbol is an asymptotic limit of the 6 -j symbol. A class ofvery general solutions to Y-B equations is also presented. This solution of the IRFmodel with infinite rapidity parameters is linked to a symmetry of the 12 - j symbol ofthe second kind.
