This is a combined JPL/CDMS catalog entry. The data have been summarized in
(1) B. J. Drouin, S. Yu, C. E. Miller, H. S. P. Müller, F. Lewen, S. Brünken, and H. Habara, 2010, J. Quant. Spectrosc. Radiat. Transfer 111, 1167
.
This work provides new data between 0.44 and 1.62 THz. Additional data were taken from
(2) Y. Endo and M. Mizushima, 1983, Jpn. J. Appl. Phys. 22, L534
;
and from
(3) W. Steinbach and W. Gordy, 1973, Phys. Rev. A 8, 1753
.
When the same transition was measured by different groups, all measurements were included in the fit with their respective experimental accuracies. The last, most accurate line has been merged.
Predictions should be viewed with caution above 2.1 THz.
Intensities were calculated based on g values obtained for the main isotopolog, see e032506.cat.
