Abstract:
We completed the first spectral line survey toward a cold, dark cloud TMC-1 (cyanopolyyne peak) in a frequency range between 8.8 and 50.0 GHz by the 45-m radio telescope of Nobeyama Radio Observatory. We detected 414 lines of 38 molecular species including 11 new molecules, such as $\mathrm{C_6H}$, CCO, $\mathrm{C_3O}$, CCS, $\mathrm{C_3S}$, HNCCC, HCCNC, $\mathrm{HC_3NH^{+}}$, HCCCHO, $\mathrm{CH_2CN}$, and cyclic $\mathrm{C_3H}$ ($c\hbox{-}\mathrm{C_3H}$), which were previously reported; only one significant line, U49536, remains unidentified. 177 out of 414 lines are reported for the first time. Some half of the detected molecules are linear carbon-chain species and their derivatives. We also discovered three new rarer isotopomers: CC${{34\atop} \mathrm{S}}, \mathrm{C_3}$${{34\atop} \mathrm{S}}$, and HDCS. Spectral charts are presented together with the observed line parameters of all detected lines. Improved molecular constants of several carbon-chain molecules obtained during the course of identification are also presented.
