The model of the anharmonic dipole moment function of the H-bonded complex AH...B is applied to C₆H₅OH(D) complexes with acetonitrile and pyridine. The frequencies and absolute intensities data for the overtones and the fundamental absorption bands in a wide spectral region (8000-50 cm^-1) and derivatives of the dipole moment function are presented and compared with ab initio calculation results on the DFT B3LYP/6-31G** level.
