•The absorption spectrum of the HD17O molecule have been studied in the range 10,000–11,300 cm−1 for the first time.•Centers and intensities of 1137 spectral lines of 12 vibrational bands of the HD17O molecule were obtained.•List of 364 experimental energy lines for 9 vibrational states (102), (080), (400), (003), (211), (051), (131), (320), and (032) was compiled. We report our investigation of the HD17О absorption spectrum in the range of 10,000–11,300 cm−1. The measurements were performed using an IFS-125 M Fourier spectrometer with a resolution of 0.02 cm−1 at a pressure of 29 mbar and an optical path length of 2400 cm. An EDEN-1L53 LED was used as a light source giving a maximum radiation intensity in the region of 0.95 µm. The absorption spectrum was analyzed using a set of software programs capable of searching for spectral lines, fitting line parameters, and making line assignments. As a result of the analysis, experimental information was obtained for the first time on the parameters of 1137 spectral lines assigned to 12 vibrational bands of HD17О, and 364 vibrational-rotational energy levels of the (022), (102), (080), (400), (003), (211), (051), (131), (320), (032), and (112) vibrational states were determined. The obtained experimental results are compared with calculated data.
