Investigation of broadening and shift of vapour absorption lines of H216O in the frequency range 7184 – 7186 cm-1

We present the results of investigation of water vapour absorption spectra in the 7184 – 7186 cm^-1 range that is of particular interest from the viewpoint of possible application of the data obtained for monitoring water vapour in the Earth's stratosphere. The doublet of H₂¹⁶O near ν = 7185.596 cm^-1 is analysed. The coefficients of broadening and shift of water vapour lines are found in the selected range in mixtures with buffer gases and compared to those obtained by other authors.
