In a series of publications, starting in 1992, we presented detailed analyses of changes in the fluorescence and absorption spectra of all‐trans‐1,6‐diphenyl‐1,3,5‐hexatriene, ttt‐DPH, that allowed their resolution into the pure spectra of two contributing species. Consistent with theory, we assigned the absorption and fluorescence of the major and minor species to the s‐trans,s‐trans‐ and s‐cis,s‐trans‐conformers of ttt‐DPH, respectively. Catalán criticized our use of isopolarizability conditions to achieve improved analyses, and we responded. He has now repeated his criticism in “Catalán, J. On the temperature‐dependent isomerization of all‐trans‐1,6‐diphenyl‐1,3,5‐hexatriene in solution: A reappraisal. J. Phys. Org. Chem. 2022, ASAP,” revealing persisting misconceptions. Not wishing to leave the casual reader with the impression that there are valid reasons for considering our work invalid or, at best, controversial, we respond again.
