Scientific paper

We present new Keck telescope spectra of the first QSO claimed to show deuterium absorption: Q0014+813. Improved signal on the Lyman series absorption lines gives more accurate information on the hydrogen absorption and more accurate predictions for the position, width, and shape of the associated deuterium absorption. There are three reasons why the absorption line near the expected position of D in the absorption system at z_abs=3.32 is not primarily D: (1) it is 17+/-1 km s^-1 from the expected position, (2) it is too wide, and (3) it does not have the expected profile, which is given by the H I lines. This absorption can be explained by a single H Lyalpha line at a different redshift. Any absorption from D would be completely blended with this additional H absorption. We find 0
