The experimental line list can be accessed with source codes. The purely K-dependent terms A, D_K etc. were assumed to agree with those of the main isotopolog, see e041505.cat.
The calculations are probably reliable throughout.
The vibrational identifier 0 indicates levels with k ≤ 0, and 1 indicates levels with k > 0.
Note: The partition function values below refer to the ground vibrational state only. Vibrational correction factors have been derived in the harmonic approximation.
