ABSTRACT The high resolution laboratory spectrum of hot water vapour has been recorded in the 500–13 000 cm −1 wavenumber range and we report on the analysis of the 4750–13 000 cm −1 (0.769–2.1 μm) portion. The emission spectrum was recorded using an oxy‐acetylene welding torch and a Fourier transform spectrometer. Line assignments in the laboratory spectrum as well as in an absorption spectrum of a sunspot umbra were made with the help of the BT2 line‐list. Our torch spectrum is the first laboratory observation of the 9300 Å‘steam bands’ seen in M‐stars and brown dwarfs.
