//Astron. Astrophys.// **688**, Art. No. L13 (2024).\\
NC<sub>3</sub>S in it <sup>2</sup>π<sub>3/2</sub> lower spin ladder was detected through five consecutive transitions with 23/2 ≤ //J'// ≤ 33/2 between 33.0 and 47.5 GHz in the course of a molecular line survey of the prototypical cold dark molecular cloud TMC-1 carried out with the Yebes 40 m radio telescope. The first two lines display somewhat and barely resolved <sup>14</sup>N hyperfine structure splitting, respectively. The next two lines are somewhat broadened, and the last line is blended. Members with //n// = 2 and //n// ≥ 4 were not detected. The abundance ratios of NCS/NC<sub>3</sub>S is about 5.6.\\
