A technique is developed for measurement of shift coefficients of absorption lines using intracavity laser spectroscopy. Line sifts for the H2O ν1 + ν2 + ν3 and ν2 + 2ν3 bands are measured in the region of 9403-9414 см-1 with the aid of an intracavity Nd:glass laser spectrometer. The shift coefficients of eight H2O absorption lines when inducing by pressure of O2, N2, and atmospheric air are between -0.004 and -0.029 сm-1/аtm.
