The rotational dipole moment was measured by Scharpen {\it et. al}, infrared transition intensities were matched to

This entry replaces catalog entries for the bending mode ($\nu_2$) and its overtone (2$\nu_2$) which were previously curated separately as entries c044009 and c044012, respectively.  In addition to these states, the other fundamental modes are also part of this entry.  This table describes the state identifiers for the various vibrational quanta.
