A survey of 63 nearby spiral galaxies for hydroxyl emission has been completed using the 305-m telescope of the Arecibo Observatory. The aim was to detect the main lines at 1667 and 1665 MHz in LTE emission, as observed in dark clouds and most GMCs in the Galaxy. No OH emission was detected, but limits have been set on the OH column densities of these galaxies. 23 references.
