The v designations separate vibrational levels and torsional sub-levels as follows:

\begin{table}[h]
\begin{tabular*}{\hsize}{@{\extracolsep{\fill}}c|c|c}
    & v'  &  v    \\
\hline
AA  & 0   &  0   \\
EE  & 0   &  1   \\
EA  & 2   &  1   \\
AE  & 1   &  1    \\
\end{tabular*}
\end{table} 

Note that the EE and EA states are
treated as l-doubling pairs. The lines were fit to a Hamiltonian that included terms up 
to the sixth power in angular momentum. Dependence on K expected from an IAM treatment
was incorporated using both Energy and B+C Fourier series with fixed ratios of
sine and cosine terms in $2 \pi \rho_a K /3$. The quality of the fit was, on the average, 
about 1.6 experimental uncertainty. The EE and EA states have both b and c type lines,
while the AA and AE states have only b type lines.

The full vibration-torsion-rotation partition function, including corrections for states
not included in the compilation, is utilized for this catalog entry.  The rotational 
partitioning is from Groner et al (2002).
