Simultaneous analysis of rotational and vibrational-rotational spectra of DF and HF to obtain irreducible molecular constants for HF
2011, Chemical PhysicsCitation Excerpt :Recently, two benchmark measurements of the rotational transitions have been made: Cazzoli and Puzzarini [27] observed a Lamb-dip spectrum of the J = 1–0 transition with a microwave spectrometer, while Cazzoli et al. [28] measured the rotational transitions from J = 2–1 to 5–4 using a tunable far-infrared (TuFIR) spectrometer. A data set of the reported high-resolution rotational and vibrational–rotational spectra for a single isotopologue HF [1–8] has previously been analyzed using a non-Born–Oppenheimer Hamiltonian [6], which yielded values of physically meaningful molecular parameters for any combination of isotopologues; choices of the fitting parameters for the case of a single isotopogue HF and that of two isotopologues DF and HF have been reported in Ref. [6] and in the present study, respectively. The spectral data of DF in the electronic ground state 1Σ+ were taken from the following papers: one Lamb-dip microwave spectrum of the J = 1–0 transition given by Cazzoli and Puzzarini [27], four TuFIR rotational transitions from J = 2–1 to 5–4 observed by Cazzoli et al. [28], 102 FTS rotational transitions of up to v = 3 state, and 186 FTS vibrational–rotational transitions up to the v = 5–4 band reported by Ram et al. [3] excluding one microwave transition.
