Scientific paper

Weighted column densities have been calculated for neutral atoms and ions of most elements and for many molecules in 6 selected model atmospheres of red-giant stars (2500 ≤ Teff ≤ 4000 K) with solar composition. These comprise the most abundant molecules from a total of about 1600 compounds analyzed. This calculation provides a guide for identification of new molecular bands in cool stellar spectra and for laboratory analysis of those molecules of stellar interest which are as yet not studied spectroscopically.
