The transition frequencies were published
by
(1) C. Degli Esposti, L. Dore, C. Puzzarini, M. Biczysko,
J. Bloino, L. Bizzocchi, V. Lattanzi, and J.-U. Grabow,
2018, Astron. Astrophys., 615, Art. No. A176.
Earlier data of very limited extent were omitted.
Some higher order spectroscopic parameter were estimated from those
of the related aminoacetaldehyde molecule. Transition frequencies with
calculated uncertainties exceeding 0.2 MHz should be viewed with caution.
The 14N hyperfine splitting can be resolved
for low values of J. Therefore, a separate
hyperfine calculation is provided up to J = 10
and up to 120 GHz along with
partition function values.
The dipole moment components were determined in

1977, J. Mol. Spectrosc., 66, 389.
