Abstract
A detailed list of line identifications of the far UV spectrum of the O4V((f)) star 9 Sagittarii (HD 164794) in the wavelength range λλ1174-2000 Å is presented. The identification is based on two spectra recorded in 1981 (on 16 April—SWP 13729 and on 24 August—SWP 14805) by the International Ultraviolet Explorer (IUE). In the list many unclassified lines are included. The radial velocities of all lines, classified and unclassified, are measured for both spectra and the mean velocities for different ions are discussed.
