Data on the absorption coefficient of H2O in binary mixture with N2 in UV region of spectra are presented. With the use of the high sensitivity photoacoustic spectrometer, the following values of the absorption coefficient were found: 2.3 × 10-9cm-1 · Pa-1 (λ = 255 nm), 0.9 × 10-9 cm-9 · Pa-1 (λ = 271 nm), and 1.6 × 10-9cm-1 · Pa-1(λ = 289 nm).
