We have calculated the ionization of the elements O, C, Mg, Si, S, and Fe and the dissociation of the molecules CO, OH, NH, CH, SiO, CN, C2, and H2O in the circumstellar envelope (CSE) of the red giant ? Andromedae (K3 III) due to the ultraviolet radiation of the chromosphere. This calculation is based on the penetration of the chromospheric UV radiation into the CSE and its effect on the wavelengths of absorption of the species listed. We show that O, C, Mg, Si, Fe, and SiO, which are important for dust formation, survive the harsh non-LTE environment close to the central star of ? And. Some implications for dust formation in the inner region of the CSE of ? And are presented.
