  We discuss the possibilities of the BaSeL models in its lowest temperature
boundary (Teff ~ 2500 K for cool giants) to provide the Teff of AGB stars. We
present the first step of our work, by comparing our predictions for the AGB
star R Fornacis with the results of Lorenz-Martins & Lefevre (1994) based on
the dust spectral energy distribution.
