Dynamic multi-coupling coefficients are introduced to describe SU (2) couplings in quantum many-body systems in which the coupling coefficients of N angular momenta are parameter-dependent. It is shown that these dynamic multi-coupling coefficients in a spin-interaction system for arbitrary spin can be determined by solving a set of nonlinear algebraic equations using an algebraic Bethe ansatz.
