- Abstract
We have analyzed the parameters of the Franck-Condon and Herzberg-Teller interactions, which form the fine-structure spectra of diphenylbutadiene substituted derivatives with the general formula X-Ph-(C=C)2-Ph-Y (where X, Y = H, NO, N(CH), and NH are the substituents in different combinations) in solutions of n-paraffins at 4.2 K. The influence of substituents on the vibronic parameters of characteristic bands that describe the states (vibrations, types of deformations upon excitation) of the phenyl rings and diphenylbutadiene polyene bridge has been considered. Data on the influence of the H, NO, N(CH), or NH terminal fragment on the parameters of the intra- and intermolecular interactions of diphenylbutadiene substituted derivatives have been presented.
