We study the properties of the color-singlet compound states of Reggeized gluons in multicolor QCD using their relation with non-compact two-dimensional Heisenberg spin magnets. Applying the methods of integrable models, we calculate their spectrum and discuss the application of the obtained results to high-energy asymptotics of the scattering amplitudes in perturbative QCD.
