The microwave transition frequencies were reported by
(1) M. Araki, M. Sanz-Novo, C. P. Endres, P. Caselli, V. M. Rivilla, I. Jiménez-Serra, L. Colzi, S. Zeng, A. Megías, Á López-Gallifa, A. Martínez-Henares, D. San Andrés, S. Martín, M. A. Requena-Torres, J. G. de la Concepción, and V. Lattanzi, 2026, Nat. Astron. 10, 401.
The entry was truncated at J = 55 and 150 GHz because of the limited line list. Transitions with uncertianties exceeding 0.1 MHz should be viewed with great caution. Transitions with ΔKa = 2 should be viewed with additional caution. b-type transition can not be calculated reliably.
The dipole moment is from a quantum chemical calculation in (1).
