LED-Based Fourier-Transform Spectroscopy: HD16O Absorption Spectrum in 0.6-μm Spectral Region
A high-resolution vibrational-rotational absorption spectrum of НD16О molecule has been studied in the visible region from 16 600 to 17 400 cm–1 using LED-based Fourier-transform spectroscopy. The spectrum was recorded using a IFS-125M Fourier-transform spectrometer with a resolution of 0.09 cm−1. A high-brightness 3HP LED was used as a source of radiation. For the measurements, we used a White-type multipass cell with an optical path length of 2880 cm. The spectral line parameters (line centers and intensities) were derived from the spectral analysis. The linelist contains more than 300 transitions to (005) and (104) vibrational states. The results obtained have been compared with the calculated and experimental data of other authors.
