* For a detailed analysis of the ℓ-doubling and Fermi resonances in N2O see [76028] and the results in the tables:
Molecular constants for 14N216O and
Molecular constants for 14N15N16O, 15N14N16O, and 14N218O.a With the exception of the (0, 22, 0) state the c and d labels associated with the ℓ quantum number correlate with the L (lower) and U (upper) labels, respectively, in the table: Microwave spectrum of N2O, while the reverse correlation holds for the (0, 22, 0) c and d states.

a All experimental measurements from [76028], except for the (0, 33 0) state, were included in the analysis. The values of Δ1 and Δ2 were determined from infrared data.
b Here α1* = α1 - 2γ11 - 2γ12 - γ13 and α2* = α2 - γ12 - 2γ22 - γ23.
c The condition γℓℓ = qJJ = 0 was employed.
