Moderate dispersion (25-35 A/mm) spectra were obtained from two carbon stars, LW Cyg and Y Tau, in a wide range of wavelengths (lambda lambda 3400-6800 A) with the 6 m echelle-spectrometer ZEBRA and two dimensional photon-counting system. Spectral feature identification was carried out from 3800 to 6300 A. Most of the bands are due to C2, CN, and SiC2, however, atomic lines of the iron peak and s-process element also are represented. Lw Cyg have intense isotopic carbon bands. The wavelengths and band-intensity were estimated.
