The entry refers to the lowest energy conformer. Its MW transition frequencies (15–40 GHz) were taken from
(1) K.-M. Marstokk, H. Møllendal, and Y. Stenstrøm, 1992, Acta. Chem. Scand. 46, 432.
The frequency calculation was truncated at J = 72 and 320 GHz. The line list is quite extensive, but higher J transitions with large asymmetry splitting are lacking as are R-branch transitions with higher J. Therefore, calculated transition frequencies above 80 GHz should be viewed with some caution, and those with calculated uncertainties exceeding 0.1 MHz should be viewed with great caution. The entry should be sufficiently accurate for cold sources and may still be acceptable for luke-warm sources (~50 K).
The experimental dipole moment components were taken from
