### Abstract

Line mixing effect has been studied for five pairs of H_{2}O lines perturbed by N_{2}, Ar and He. Two pairs of lines (in terms of the rotational quantum numbers J, K_{a}, and K_{c}) [101] ← [212], [212] ← [303] and [303] ← [212], [212] ← [101] belong to the ν_{2} band, two pairs of lines [312] ← [413], [321] ← [422] and [431] ← [330], [422] ← [321], belong to the ν_{1} + ν_{2} + ν_{3} band and fifth pair of the lines [541] ← [652], [541] ← [634] belong to the 3ν_{1} + ν_{2} and 8ν_{2} band, respectively. Pressure broadening coefficients of H_{2}O (half-widths, pressure shifts and off-diagonal relaxation matrix elements) have been calculated for all lines and for two pair of lines from the ν_{1} + ν_{2} + ν_{3} band perturbed by N_{2} and Ar they have been obtained experimentally.
