Notes.

(a)

Quantum numbers of the upper and lower levels.

(b)

Frequency uncertainty.

(c)

Upper level energy.

(d)

Upper level degeneracy.

(e)

Einstein coefficient for spontaneous emission.

(f)

Measured rms noise level.

(g)

Peak opacity of the synthetic line.

(h)

Frequency range over which the emission was integrated.

(i)

Integrated intensity of the observed spectrum in brightness temperature scale. The statistical standard deviation is given in parentheses in unit of the last digit. Values marked with a star are used in the population diagrams shown in Figs. 1c and d.

(j)

Integrated intensity of the synthetic spectrum of 13CH3CH213CN.

(k)

Integrated intensity of the model that contains the contribution of all identified molecules, including 13CH3CHCN.
