Scientific paper

Spectra of the radio QSO 1442 + 101 have been obtained at a resolution of 2 A FWHM from 3300 to 6200 A. Two absorption-line systems at z(ab) = 2.0703 (probable) and 2.5632 (certain) have been identified with lines of hydrogen and heavier ions, and 30 more possible systems have been found with only hydrogen lines. No H2 was found at z(ab) = 2.651 or 3.092, where Levshakof and Varshalovich (1979) reported a detection.
