“…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).…”

“…a Fit including all rotational transition frequencies available: This work, Lattanzi et al (2008), Baskakov et al (1999), Bellet et al (1971), and Ruben & Kokolich (1974 frequency lines were fitted, which allowed us to determine two additional octic centrifugal-distortion constants, L J and l J , with respect to our previous fit (first column of Table 2). As for DCOOH, an overall agreement is observed.…”

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.

“…So far a number of microwave, low-, and high-resolution infrared measurements (4 -18) were made on various bands of HCOOH, DCOOH, H 13 COOH, HCOOD, and DCOOD. In particular, high-resolution studies for HCOOD were limited to the 3 band (12,18), the 5 band (14), and the 7 and 9 bands (15).…”

“…(1) for some new transitions assigned in the present work were as high as 0.15 cm −1 . This circumstance impelled us to perform a new fit of the ν 5 band with the more precise ground state parameters (4). Substitution of these parameters into the expression [1] yields for the planarity sum the much better value of 5.31 (MHz) 2 .…”

“…The maximum value of J is 67. C 2001 Academic Press Key Words: formic acid, FTIR spectrum, deuterated.High-resolution infrared spectra of the parent and deuterated substituted isotopic species of the trans-rotamer of formic acid (HCOOH) have been extensively studied in recent years (1,4,(6)(7)(8)(9)(10)(11)(12)(13)(14)(15), due to detection of its significant presence in interstellar space. The present work deals with the investigation of the ν 5 band of HCOOD though it was quite recently measured under high resolution by Goh et al (1).…”
