The experimental frequencies have been reported by

Some parameters were kept fixed to values determined for the main isotopic species.
Mar. 2012: The individual states have been set up differently to describe the parity of the state l = 2 correctly. Now state number 0 refers to l = 0+, state number 1 to l = 0, and state number 2 to l = 2. Version number and date of entry have been retained.
The Hamiltonian converges slowly. This is probably caused by the rotational interaction with v7 = 3. Predictions may be at least fairly reasonable up to about 350 or even 400 GHz; they should be viewed with great caution above 600 GHz.
Vibrational contributions to the partition function of H13CCCN are also available.
The dipole moment was assumed to agree with that of the main isotopolog, see e051505.cat.
