The high resolution infrared spectrum and molecular structure of the superacid H2F+ by velocity modulation laser absorption spectroscopy

Article abstract of DOI:10.1063/1.447449

The gas phase infrared spectrum of the fluoronium ion (H2F⁺) was recorded with Doppler- limited resolution between 3080 and 3520 cm^-1 by velocity modulation laser absorption spectroscopy of a hydrogen plasma containing 5 percent HF.One hundred and nine of the observed transitions were assigned to the symmetric stretch (ν₁) and 217 to the asymmetric (ν₃) stretch.A least squares analysis of v3 transitions up to J =11 and K_a = 6 and ν₁ transitions up to KQ = 4 with Watson's S-reduced Hamiltonian yielded rotational constants and centrifugal distortion constants for the vibronic ground state and for the two excited states.Small Coriolis interactions between ν, and ν₃ levels were observed, but were not treated explicitly.The band origins for ν₃ and ν, are 3334.6895(26) and 3348.7078(36) cm^-1, respectively.The r_o structure of H2F⁺ was determined as: r_HF = 0.9577 Angstroem
