Abstract

We examine the H I content of spiral galaxies in groups by using a catalog of loose groups of galaxies identified in a magnitude-limited sample (m_z ≤ 15.7) spanning the range 8^h ≤ α ≤ 18^h in right ascension and +9° ≤ δ ≤ +15° in declination. The redshift completeness of the galaxy sample is approximately 95%. No significant effect of H I depletion is found, although there may be a hint that the earliest type spirals are slightly deficient.
