Excitation spectrum and thermodynamic properties of spin-1 Bose condensates under the single-condensate assumption were studied. Higher-scattering effects were considered. Analytical expressions of the excitation spectrum and thermodynamic quantities were obtained. Self-energies were evaluated within the on-shell approximation. The resultant data were analyzed in detail.
