The paper reports the detection in TMC 1 of low order rotational transitions arising from the molecular species identified with C3N and C4H by Guelin and Thaddeus (1977) and Guelin, Green, and Thaddeus (1978). The hyperfine structure of the transitions is completely resolved for both species. An analysis of this structure confirms the identifications of C3N and C4H and yields a precise determination of the fine and hyperfine constants. The C4H N equals 2-1 line is surprisingly strong in TMC1 and is detected in all seven dark clouds which were surveyed. The C4H/HC3N abundance ratio is found to be about the same (approximately 3) in these clouds. This ratio, in contrast, is smaller in hotter clouds such as SgrB2.
