At Nancay, 21-cm H I line observations were made of 15 spiral-dominated loose groups of galaxies, divided into two samples: an "interacting" sample containing at least one pair of interacting galaxies, and a "control" sample having no optical evidence of interactions or morphological disturbances among the group members. The interacting sample consists of 62 galaxies representing 9 different groups, and the control sample contains 40 galaxies representing 6 groups. Of the 91 galaxy and galaxy pairs observed, 74 were detected, while upper limits were placed on the remaining 17 objects. These homogeneous H I data, which will be used in future analyses, provide comparative information on the H I content of groups and serve as a probe of the vicinity of the target spirals for H I clouds or very low surface brightness gas-rich galaxies. Key words: galaxies: distances and redshifts - galaxies: general - galaxies: interactions - galaxies: ISM - radio lines: galaxies
