The parameters of Franck–Condon and Herzberg–Teller interactions that form the fine-structure spectra of all-trans diphenyl polyenes in n-paraffin solutions at 4.2 K are analyzed. The effect the length of a polyene chain has on the emergence of benzene fragment bands is considered for four all-trans-diphenyl polyene compounds that differ by the number of π-conjugated bonds in the polyene chain.
