On the nature of excited electronic states in cyanine dyes: implications for visual pigment spectra

Uri Dinur, Barry Honig, Klaus Schulten

Research output: Contribution to journalArticle

Abstract

CNDO/S CI calculations are carried out on polyenes and on cyanine dyes. In contrast to polyenes, doubly excited configurations have a strong effect on the first optically allowed excited state in cyanines. Protonated Schiff bases of retinal are closely related to cyanine dyes, with important consequences for models of visual pigment spectra and photochemistry.
