Our paper is devoted to analysis of measured and calculated lineshifts pressured by nitrogen in the v₂ band of the water vapor molecule, and especially to the rotational dependence of the lineshifts. The data have been obtained for 150 lines in 1850 - 2230 cm^-1 spectral region. The room temperature measurements were made with FT- spectrometer in Paris University at the spectral resolution 0.005 cm^-1 at three different pressures of the sample (water pressure -- 1 Torr, nitrogen pressure -- 117 and 203 Torr). A special procedure has been used to minimize the errors connected with the asymmetry of the contours due to apparatus effects. The different reduction procedures have been used to obtain the line shift coefficient values.
