The rotational transition frequencies were taken from
(1) E. Hirota, Y. Endo, S. Saito, K. Yoshida, I. Yamaguchi, and K. Machida, 1981, J. Mol. Spectrosc. 89, 223.
Also used in the fit were infrared fround state combination differences of three IR bands from
(2) G. B. Lebron and T. L. Tan, 2010, J. Mol. Spectrosc. 261, 119;
(3) T. L. Tan and G. B. Lebron, 2010, J. Mol. Spectrosc. 263, 160;
and from
(3) G. B. Lebron and T. L. Tan, 2011, J. Mol. Spectrosc. 265, 55.
Predictions with calculated uncertainties exceeding 0.3 MHz should be viewed with caution.
The dipole moment is an estimate based on the experimental value of H2CCD2 in (1).
