Scientific paper

A wide-band microwave spectral scan of TMC-1 was performed using the Nobeyama 45 m telescope and two 16,000 channel AOSs (acousto-optical radio spectrometer), for the frequency regions of 22-24 GHz and 36-50 GHz. The authors have detected seven strong lines which could not be identified with any known molecules, including the U45379 which was reported in 1984 by Suzuki et al. Companion papers by Saito et al. and Yamamoto et al. report that all these lines are identified with a new series of carbon chain molecules, CCS and CCCS.
