Even though the line list is comparatively extensive compared to, e.g., other studies on sugars, it is still very limited. The calculation was truncated at J = 25 and 120 GHz. Caution is advised for extrapolations above J of 15 or Ka of 6; particular caution is necessary for transition frequencies with calculated uncertainties exceeding 0.1 MHz. The calculation may be good enough for searches in cold sources.
The dipole moment components are from a quantum chemical calculation in (1).
