Water vapor line strengths in the 1-μm region

Abstract The line strenghts of H 2 O bands ν 1 + ν 2 + ν 3 and ν 2 + 2 ν 3 have been measured using a high-resolution Nd-glass single-mode laser spectrophotometer. The parameters of 33 lines were found by fitting a Voigt contour to experimental line profile. The vibration-rotation interaction affecting the line strength was taken into account by using the F factor in the three-parametric form, and its constants for ν 1 + ν 2 + ν 3 and ν 2 + 2 ν 3 bands were found. There is a good agreement between line intensities calculated using these constants and the experimental values.
