Scientific paper

Spectra of TB 0933 + 733 in the 3400-6300 A range were obtained with the 6-meter telescope at a resolution of about 4 A. The structure of the Lyman-alpha emission line profile suggests the presence of Si III (lambda0 1206), H I (lambda0 1216), and N V (lambda0 1240) lines. Twenty-seven absorption lines are listed, some of which are identified as the ion lines of heavy elements. The presence of the line system z(abs) = 2.3336, containing the strongest Lyman-alpha absorption line (W0 = 5.2 A), is confirmed.
