Abstract
We present SWS01 spectra of the carbon-rich long-period variables R Scl and T Dra taken at several pulsational phases and compare them with synthetic spectra. The model spectra are based on hydrostatic and dynamic model atmospheres as described in the contributions by Hofner et al. and Loidl et al.. The hydrostatic model atmospheres approximately cover the temperature range expected for R Scl during a pulsational cycle. The dynamical model (R7OS14) is comparable to R Scl with regard to the period, initial Teff, bolometric amplitude and low mass loss rate but does not attempt to specifically model this star.
