Scientific paper

The resonance line of Sc II at 3642.785 A has been sought in the interstellar spectrum of Zeta Oph, resulting in an upper limit N(Sc II) not greater than 8.6 billion/sq cm and a depletion of this element at least by a factor of 200, if Sc III contributes a negligible column density. The present upper limit may be somewhat below the level expected under the grain-formation model for interstellar depletions, and is consistent with the abundance expected if the depletions are due to gas-grain collisions. The new limit on this element helps to support the hypothesis that species within a specific range of ionization potential are preferentially depleted.
