The basic physical ideas and the general structure of the Hamiltonian of the quasiparticle--phonon nuclear model are discussed in relation to spherical nuclei. Equations are obtained for the energy and structure of the single-phonon states with allowance for the various components of the effective internuclear forces (separable multipole, spin--multipole, spin--isospin--multipole, etc.). The properties of single-phonon excitations and some general properties of nuclear operators are discussed in detail. The results of calculations made with different radial dependences of the effective separable forces are compared. The accuracy of the random-phase approximation in spherical nuclei is investigated.
