The observed transition frequencies have been published by
(1) S. Brünken, H. S. P. Müller, K. M. Menten, M. C. McCarthy, and P. Thaddeus, 2008, Astrophys. J., 676, 1367.
With respect to the Apr. 2008 entry, additional millimeter wave data were included. These were published by
(2) P. Kania, M. Hermanns, S. Brünken, H. S. P. Müller, and T. F. Giesen, 2011, J. Mol. Spectrosc., 268, 173.
Data of three isotopic species, 48TiO2, 46TiO2, and 50TiO2, have been fit together as described in (1) and (2). Predictions with uncertainties larger than 1 MHz should be viewed with caution.
The experimental dipole moment was assumed to agree with that of the main isotopic species, see e080504.cat.
