An intexrable srin model on the one-dimensional lattice is obtained from thedifferential-difference nonlinear Schr6dinger equation by introducing the conceptof gauge equivalence. The Hamiltonian for this spin model is expressed asH= - 2 I log (1 -[ .5. = .5.. . )where the spins .5. are classical three-dimensional unit vectors.
