What is SU(2) approximation to the coupling of Morse oscillators about?

We show that the SU 2 vibron model automatically gives the correct coupling between Morse oscillators as long as they Ž . only interact via the dominant DÕ s "1 selection rule. We compare the SU 2 approximation with the model introduced by Child and Lawton, where the coupling is harmonic. The well-known harmonically coupled anharmonic oscillator model Ž . HCAO can thus be modified to consistently incorporate anharmonicity maintaining an analytic framework. We also discuss Ž . the classical phase space for the Morse oscillator case and its relation to the harmonic and SU 2 approximations.
