Higgs algebras are used to construct rotational Hamiltonians. Thecorrespondence between the spectrum of a triaxial rotor and thespectrum of a cubic Higgs algebra is demonstrated. It is shownthat a suitable choice of the parameters of the polynomial algebraallows for a precise identification of rotational properties. Theharmonic limit is obtained by a contraction of the algebra,leading to a linear symmetry.
