Thioethenylidene, C<sub>2</sub>S, was identified by its four //N<sub>J</sub>// = 10<sub>11</sub> – 9<sub>10</sub> to 11<sub>12</sub> – 10<sub>14</sub> transitions with rest frequencies between 131.5 and 144.3 GHz.

S. Muller, A. Beelen, M. Guélin, S. Aalto, J. H. Black, F. Combes, S. J. Curran, P. Theule, and S. N. Longmore\\
used the Australia Telescope Compact Array (ATCA) to study the molecular content of a foreground galaxy at //z// = 0.89 (FG0.89 consisting of two subsources, FG0.89SW and FG0.89NO) in absorption toward the quasar PKS 1830-211:\\

The low energy fine structure lines //N<sub>J</sub>// = 5<sub>5</sub> – 4<sub>3</sub>, 6<sub>5</sub> – 5<sub>4</sub>, and 7<sub>6</sub> – 6<sub>5</sub> with rest frequencies near 57.2, 69.3, and 81.5 GHz, respectively, were detected in absorption.
