High-resolution Fourier transform spectra of monoisotopic \(\mathrm{H}_{2}{ }^{\text {k0 }}\) Se have been recorded with a resolution of \(7 \times 10^{-3} \mathrm{~cm}^{-1}\) in the \(4210-4850 \mathrm{~cm}^{-1}\) spectral range. Their rovibrational analysis  have been recorded in the 10 - and \(4.3-\mu \mathrm{m}\) spectral regions where the \(\nu_{2}\) and the \(2 \nu_{2}, \nu_{1}\), and \(\nu_{3}\) bands of this molecule absorb, respectively. The \((0 \mid
The Fourier transform spectra of \(\mathrm{CICN}\) have been recorded between 2860 to \(3030 \mathrm{~cm}^{-1}\) with a resolution of \(0.0026 \mathrm{~cm}^{-1}\). The \(\nu_{1}+\nu_{3}\) and \(2 \nu_{2}+\nu_{3}\) bands and the associated hot bands have been analyzed. A band-by-band analysis has bee
A high-resolution \(\mathrm{FT}\) infrared spectrum of \(\mathrm{H}_{3} \mathrm{Si}^{70} \mathrm{Br}\) (resolution \(0.0022 \mathrm{~cm}^{-1}\) ) in the region \(830-1050 \mathrm{~cm}^{-1}\) was used to analyze the fundamental bands \(\nu_{2}\left(A_{1}\right)\) and \(\nu_{5}(E)\). A total of 4392 t
The infrared spectrum of SCF 2 was recorded in the 1000 -1400 cm Ϫ1 region with a resolution of 2.5 ϫ 10 Ϫ3 cm Ϫ1 . The rotationally resolved 1 and 4 band systems were studied for the first time, and altogether 11 500 transitions were assigned. Both fundamentals are involved in strong anharmonic (Fe
The very weak bands nu1 + 2nu2 + 3nu3 and 4nu1 + nu3 of 16O3 have been observed for the first time, using the Fourier transform spectrometer (FTS) of Reims and the usual experimental setup providing a large product p x l of approximately 38 Torr x 36 m. The upper levels of these A-type bands which a
