Notes.

^(a)

Rotational partition function calculated using the asymmetric top approximation (Townes & Schawlow 1975).

^(b)

Vibrational partition function calculated using harmonic oscillator approximation on the 21 normal modes, i.e., including the two low torsional states ν₁₅ and ν₁₁. The total partition function is given by the product of the rotational (Q_rot) and vibrational (Q_v) partition function.
