//Astrophys. J.// **948**, Art. No. 133 (2023).\\
The identification was made by stacking data from the GBT line survey that covers ~24.9 GHZ of the 7.9 to 36.4 GHz region. The //E// form of 1-cyano-1,3-butadiene is less abundant than the two detected cyanocyclopentadiene isomers by factors of a few, somewhat depending on the sources of the column densities of the cyclic species.\\
