Abstract

The values of broadening and shift coefficients induced by H₂ pressure for the H₂O absorption line centered at 694.38 nm (4₁₄-5₁₅ transition of 000-103 band) were measured. A nonlinear character of the H₂O absorption line center shift dependence on H₂ pressure at its increase beyond 450-500 Torr was experimentally revealed.
