Paper Abstract

A near-infrared diode laser spectrometer was used under laboratory conditions to measure the H2O line strengths and shifts by H2 and He pressure near 1.39 μm. The hydrogen and helium broadened half-widths and shifts were measured for 5 transitions. These lines from the v1 + v3 and 2v1 bands were selected because they are used for the “Spectrometre a diodes lasers” SDLA spectrometer (France) and to complete a set of isolated and quite strong lines with different J parameters. The experimental and calculated data are compared based on the semiempirical approximation in the absorption line broadening and shift. The helium pressure-induced shift coefficients and the hydrogen pressure-induced shift coefficients have opposite signs.
