“…From this comparison it is seen that in the present work for both isotopic species rotational constants and some centrifugal-distortion constants have been improved. The improvement is roughly one order of magnitude and mainly due to the higher accuracy of the transitions Lattanzi et al (2008), Baskakov (1996), Bellet et al (1971), and Kukolich (1969 recorded up to ∼600 GHz by means of the Lamb-dip technique. In the case of HCOOD the present investigation, carried out up to 1.05 THz, allowed to determine one additional centrifugaldistortion constant, i.e., l JK , in comparison to the previous work by Lattanzi et al (2008), who recorded transitions up to 1.2 THz (Table 1).…”

“…In fact, in the literature only the diagonal deuterium quadrupole-coupling constants of HCOOD were reported (Ruben & Kukolich 1974) and these were redetermined with improved accuracy in this work. For both DCOOH and HCOOD, global fits including all data available in the literature (Lattanzi et al 2008;Baskakov et al 1999;Baskakov 1996;Bellet et al 1971;Ruben & Kukolich 1974;Kukolich 1969) were carried out. The present fits can be considered a further improvement with respect to those reported by Lattanzi et al (2008).…”

The rotational spectra of the mono-deuterated isotopologues of trans-formic acid, trans-DCOOH and trans-HCOOD, were investigated. In the millimeter-and submillimeter-wave frequency regions the Lamb-dip technique was exploited to obtain sub-Doppler resolution and to resolve the hyperfine structure due to the deuterium and hydrogen nuclei, thus enabling the accurate determination of the corresponding hyperfine constants. The experimental determination was supported by high-level quantum-chemical calculations at the coupled-cluster level of theory using large atomic-orbital basis sets. The Lamb-dip measurements were also supplemented by THz Dopplerlimited measurements in order to extend the predictive capability of the available spectroscopic parameters to higher frequencies.

“…In the fit, the lower state constants were fixed at the ground state constants obtained from the present combination-difference fit (MW, IR) given in Table 1. The band center for 4 of DCOOD was found to be 1170.799799 Ϯ 0.000020 cm Ϫ1 . In preliminary fits of the full set of assigned transitions we tried to fit the two sextic constants of 4 ; however, the rms deviation of the fit was not improved.…”

“…In this paper we report the results of the analysis of the 4 band of DCOOD which was measured with a resolution of 0.004 cm Ϫ1 . From the assignments of 111 microwave transitions (2) and 969 combination differences, we have improved the values for the rotational, all five quartic, and two sextic centrifugal distortion constants of the ground state.…”
