• Ground-based UV
• High resolution spectroscopy
• Hot stars
• Evolved stars
• Spectral atlas

We present a spectral atlas of 4 B and A stars containing spectra in a poorly studied spectral range of 305-452 nm. The atlas is based on high resolution (R=60 000) spectra obtained with the 6 meter telescope (SAO, Russia) combined with the NES-spectrograph. The procedure of spectral lines identification and compilation of the atlas is discussed in detail. Using the spectral data we thoroughly investigated the velocity field in expanding atmospheres and envelopes of hot evolved stars beta Ori, alpha Cyg and supergiant KS Per with the extreme hydrogen deficiency. The complete atlas and list of the identified spectral lines will be available via the astronomical database SIMBAD.
