Spectroscopic Investigation of Carotenoids Involved in Non-Photochemical Fluorescence Quenching

Popis výsledku v původním jazyce

This chapter will review the recent results in the field of carotenoid photophysics and relate excited-state properties of carotenoids to their potential roles in the dissipation of the singlet-excited state of chlorophyll a resulting in non-photochemical quenching (NPQ) of chlorophyll fluorescence. Investigations into the structure and dynamics of excited states of carotenoids have revealed potential mechanisms regarding the involvement of spectroscopically forbidden "dark" excited states in carotenoidrelaxation pathways. The generally accepted model for deactivation of excited states of carotenoids following photo-excitation invokes three states, the ground state S0, the first excited state S1, considered "dark" because the S0?S1 transition is forbidden by symmetry, and the second excited state S2, where the S0?S2 transition is strongly allowed. In addition to these states, a number of other excited states have been proposed to be involved in carotenoid de-excitation on the basis of
