Abstract:Moderate dispersion (25-35 Å mm–1) spectra were obtained from two carbon stars, V Cyg and WZ Cas, in a wide range of wavelengths (lambdalambda3400-6800 Å) with the echelle-spectrometer, ZEBRA, of the 6 m telescope and two-dimensional photon-counting system. Spectral feature identification was carried out from 3850 to 6200 Å. Most of the bands are due to C2, SiC2, and CN, however, particularly in WZ Cas, moderate atomic lines of the iron peak and s-process elements are also found. WZ Cas is a so-called lithium star, however, we have found no evidence for a strong line of Li. The spectra of V Cyg contain an emission line of Hbeta.
