Abstract:
    High resolution optical spectra of the unique hot R CrB star V348 Sgr are
    presented and more than 500 spectral lines of 14 elements are identified.
    The spectrum is very complex and four types of line profiles can be
    distinguished: a) pure absorption lines, b) P-Cygni lines, c) pure emission
    lines and d) P-Cygni (HeI) or emission (CII) profiles with central
    absorption reversal. The spectrum is interpreted as that of an expanding
    atmosphere of small optical thickness with wind velocities between 150 and
    200 km/s. Hydrogen is definitely present in the expanding atmosphere. The
    absorption line spectrum is very similar to that of the extreme helium
    stars DY Cen and LSE 78.

Note (1): the class is defined by:
        a: pure absorption
        b: blue-shifted absorption and red-shifted emission (P-Cygni profil)
      b/c: emission line with uncertain blue absorption
        c: pure emission
        d: central reversal in emission components of lines of Class b+c
