a

Notes.Quantum numbers are J, Ka, Kc.

b

Observed frequencies adopting a vLSR of 5.83 km s−1 for TMC-1.

c

Integrated line intensity in mK km s−1.

d

Linewidth at half intensity derived by fitting a Gaussian line profile to the observed transitions (in km s−1).

A

Line slightly blended with an unidentified line. Fit still possible and reliable.

B

A and E components are marginally resolved. Fit uncertain.

C

Line slightly blended with the J=35-34 line of DC7N. Fit still possible and reliable.

D

Data set corresponds to frequency switching with a throw of 8 MHz alone.
