We report on the discovery of two new molecules, HCCCHCCC and HCCCCS, towards the starless core TMC-1 in the Taurus region from the QUIJOTE line survey in the 31.1-50.2 GHz frequency range. We identify a total of twenty-nine lines of HCCCHCCC and six rotational transitions of HCCCCS. The rotational quantum numbers range from J u = 10 up to 15 and K a ≤ 2 for HCCCHCCC and J u = 21 / 2 up to 31 / 2 for HCCCCS. We derived a column density for HCCCHCCC of N = (1.3 ± 0.2) × 10 11 cm − 2 with a…
