| | Twelve transition with //J// = 8 to 12 and //K<sub>a</sub>// ≤ 1 were detected with the Yebes 40 m radio telescope. The CH<sub>3</sub>C<sub>4</sub>H to CH<sub>2</sub>DC<sub>4</sub>H abundance ratio of 24 ± 2 is very similar to that of CH<sub>3</sub>C<sub>3</sub>N to CH<sub>2</sub>DC<sub>3</sub>N ratio of 22 ± 2.\\ |
