In this paper, we present medium resolution spectra of the night-sky OH emission. The spectra cover the range 0.997 - 2.25 [FORMULA] with a resolution of about 8000. Line wavelengths are computed from laboratory data and are given in vacuum. A few lines due to O2 are also identified.

This new set of data can be used to calibrate the wavelength scale of spectra obtained in the near-infrared. It can also help to distinguish between the lines due to astronomical objects and lines due to the earth atmosphere.

Key words: line: identification
