The self-broadening coefficients γ and pressure-induced frequency shift coefficients δ of the ν2, ν1 + ν2, 3ν2, and ν2 + ν3 vibrational-rotational bands of D2O molecule were calculated in the framework of the semiclassical approach, taking into account the exact trajectory model. The influence of the accidental resonances on values of γ and δ was investigated. The computed coefficients γ were fitted to an empirical expression.
