Both the stretch and bend vibrational spectrum and the intensity of infrared transitions in a tetrahedral molecule are studied in a U(2) algebraic model, where the spurious states in the model Hamiltonian and the wavefunctions are exactly removed. As an example. we apply the model to silicon tetrafluoride SiF4. (C) 1995 Elsevier Science B.V.
