Notes.

a

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

b

Integrated line intensity in mK km s−1.

c

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

A

Frequency switching data with a 10 MHz throw only. Negative feature present in the data with an 8 MHz throw.

B

Frequency switching data with an 8 MHz throw only. Negative feature present in the data with a 10 MHz throw.

C

Blended exactly at the same frequency with a line of H2C4N that contributes up to 60% of the observed feature. Assuming the remaining intensity is produced by this transition of fulvenallene, then the frequency of the transition may be 39354.949±0.030 MHz.

D

Blended with another feature. Fit still possible.

E

Upper limits correspond to three times the rms of the data. In these cases, frequencies correspond to those calculated with the recommended constants of Table 1.

F

Negative feature in both frequency switching data sets.

G

Line too broad. Probably blended with another feature.

H

Blended with a strong U feature. Unreliable fit.

I

Marginal detection.
