    Group-theoretical methods are used to identify the nonvanishing parameters τ and establish relations between them in the effective Hamiltonians which describe rotation and motion with large amplitude. The cases considered are 1) bending vibration in molecules of the type XY2 and XYZ and 2) inversion vibration in pyramidal molecules of the type XY3. For the latter type of molecule, the symmetry properties of the parameters τ in the effective centrifugal Hamiltonian for quasidegenerate inversion states are investigated. The general form of this Hamiltonian and its symmetry properties are established and studied in an arbitrary order in the small parameter.
