In this study, the authors present the technique of tunable diode laser spectroscopy and the spectroscopic parameters of 13 lines of H2O in the 11980-12260/cm spectral region. Spectra were recorded at room temperature for a wide range of pressures (2-15 Torr for pure H2O and 50-760 Torr for H2O in air). Line parameters were adjusted from experiments using the least square method, Fortran and three line-shape models: the Voigt profile (VP), the (hard collision) Rautian profile (RP) and the speed dependent Voigt profile (SDVP). A comparison between the results with the HITRAN database 2012 shows good agreement.
