The lines were summarized in
(1) L. Nemes and M. Winnewisser, 1976, Z. Naturforsch. 31a, 272.
With respect to the Nov. 2003 entry, additional measurements between 222 and 324 GHz have been considered. They were published by
(2) A. Guarnieri, 2005, Z. Naturforsch. 60a, 619.
The line list was kindly provided by the author. Some higher order centrifugal distortion constants were kept fixed to values estimated from the main isotopomer, see e042501.cat.
NOTE: No spin-statistics have to be considered because of the low symmetry of the molecule !
The dipole moment was assumed to be the same as for the main isotopomer, see e042501.cat.
