Abstract
The rotational spectrum of DF in the 1.3-3.3 THz frequency region has been observed by means of a tunable far-infrared spectrometer. The J + 1 ← J, with J = 1-4, rotational transitions of DF have been recorded with an accuracy of the order of 50-200 kHz. These measurements, in conjunction with the hyperfine components of the J = 1 ← 0 transition recently observed [Cazzoli and Puzzarini, J. Mol. Spectrosc. 231 (2005) 124-130] and the rotational transitions up to J = 47 [R.S. Ram, Z. Morbi, B. Guo, K.-Q. Zhang, P.F. Bernath, J. Vander Auwera, J.W.C. Johns, S.P. Davies, Astrophys. J. Suppl. Series 103 (1996) 247-254] consented to improve the ground state rotational parameters of DF. © 2005 Elsevier Inc.
