A comparative analysis of the parameters of the Franсk-Kondon and Herzberg-Teller interactions forming the fine-structure spectra of α, ω-tetrafluorodysterylbenzene, 1,4-distyrylbenzene and stilbene is carried out. It is shown that the introduction of fluorine substituents leads to reduce the dipole moment of the molecule, and as a result, reduces the values of the parameters of intermolecular interaction. It is concluded that the parameters of intra- and intermolecular interactions, forming the fine-structure spectra of the selected molecules, make it possible to use the fragmentary approach in the description of fundamental bands.
