Observed transitions of cis-CH3CHCHCN (cis-crotononitrile) towards TMC-1. Line parameters are given in Table A.4. Internal rotation splits the lines into two components, E and A, which correspond to the low and the high frequency components in each panel, respectively. The abscissa corresponds to the rest frequency assuming a local standard of rest velocity of 5.83 km s−1. The ordinate is the antenna temperature corrected for atmospheric and telescope losses in milli Kelvin. The red line shows the synthetic spectrum derived for Trot=7 K and N(cis-CH3CHCHCN)=1.3 × 1011 cm−2.
