| Abstract: | A four essential‐state model is proposed for a detailed description of optical spectra of a family of anionic polymethine dyes. Extensive spectroscopic data from the literature are quantitatively described within a model that accounts for non‐adiabatic electron‐vibration coupling and for polar solvation. |
