Based on numerous experimental data and results of ab initio calculations of intensities of the fundamental v_s(XH) mode of the XH...Y (X = F, Cl, O, N) complex and of the 2v_s overtone of the low-frequency v_σ(X...Y) valence vibrational band and combination v_s ± v_σ bands, parameters of the model induced dipole moment are found. The data for ∼35 complexes of alcohols, amines, phenol, HCl, and HF are analyzed. It is shown that the dependence of the induced dipole moment on the coordinate r(XH) is described by a power function with the exponent a ≈ 3 in all systems studied. The individual contributions to the matrix element of the transition dipole moment for the fundamental v_s mode are analyzed for the example of the HCN...HF complex using derivatives of the dipole moment of the complex and anharmonicity constants calculated from the model. Expressions and numerical estimates are obtained that describe the temperature dependence of the v_s band intensity with and without account for combination v_s ± v_σbands.
