Abstract: | The ν2 (CO stretch) fundamental band of formyl fluoride (HFCO) was studied in the region 1800 to 1910 cm?1 using the two techniques of intracavity CO laser Stark spectroscopy at sub-Doppler resolution and Fourier transform spectroscopy at Doppler-limited resolution. Accurate values of the molecular parameters of the ground and excited (v2 = 1) vibrational states were obtained from a combined fit of the ν2 band data and available microwave data. The results include precise determinations of the electric dipole moment components (μa and μb) of HFCO in the ground and excited states. |
