6. Summary and conclusions

We have presented a first preliminary comparison of ISO-SWS spectra of R Scl with predictions of state-of-the-art dynamical model atmospheres. Considering the uncertainties of some physical input data and the approximations used in the present models we find a good qualitative agreement for molecular features in the near infrared range. We stress the theoretical progress and the potential of analysing the spectra by using self-consistent dynamical models. Only dynamical models open the possibility to include the effects of pulsation, shock waves, dust formation and a circumstellar envelope and to investigate dynamical phenomena like line doubling due to shock waves in the atmosphere. More and better processed data from the ISO mission are becoming available, which will continue to give better constraints for the models.
