Thirty-one radio sources have been investigated for the presence of OH-line radiation in their directions. Absorption and anomalous emission lines were observed.
The equipment and methods of observation have been described by Gardner, McGee and Robinson (1967). An aerial beamwidth of 12’.5 arc was combined with a 48-channel line receiver of bandwidths 37 and 10 kHz.
