Assuming the low molecular reorientation approximation, the formulae for linear electric polarization induced in liquids composed of rigid, noninteracting, dipolar and asymmetric-top molecules in spherical solvents were derived. The Kalmykov's equation [Phys.Rev., E 65 (021101) 2001] – equivalent to the classical, noninertial Smoluchowski-Debye model of rotational diffusion was applied. In order to highlight the influence of the anisotropy of rotational diffusion tensor components and the orientation of permanent dipole moment of the molecule on the complex linear electric susceptibility, we present three-dimensional plots of the dispersion and absorption spectra, Cole-Cole diagrams for different values of the anisotropies of rotational diffusion tensor components and different frequencies of an ac electric field.
