Scientific paper

The Arecibo radiotelescope was used to scan for OH 18-cm line emissions from the Comet Crommelin as a trial for 3 arcsec resolution observations of Halley's Comet. The instrument was centered on the 1665 and 1667 MHz bands during intervals in January and February 1984. No detection of the OH 1665 and 1667 MHz lines was made above a 3-sigma limit of 9 mJy; and no detection of continuum emission at 18 cm was made above a 3-sigma level of 5 mJy.
