The dipole moment has been extrapolated and has been assumed to be equal for both states.
Some lines with larger experimental uncertainties >80 kHz have been omitted in the c051509.cat-file. Nevertheless, they have been considered in the analysis.
Vibrational contributions to the partition function of HC₃N are also available.
