A survey of 240 galaxies for hydroxyl absorption has been completed using the Arecibo
Observatory. New results include five previously unpublished strong lines in NGC 2339, IC
860, IC 883, NGC 5859, and UGC 11905. Six additional possible lines where the signal-to-
noise ratio is⪉ 3 are also included. Spectra of the 1667 and 1665 MHz transition of OH are
accompanied by 21 cm neutral-hydrogen spectra for these 11 galaxies. HI absorption
appears at the same velocity as the hydroxyl features. In general, these galaxies are�…
