Ondersoek na die opgewekte elektroniese toestande van karotenoïede in die hoofligversamelingskompleks van plante (LHCII) deur femtosekondepompproefspektroskopie

Abstract

Photosynthesis involves the main plant light-harvesting complex (LHCII) pigments (chlorophylls and carotenoids). These pigments absorb and transfer photoenergy to lower excited electronic energy states. Carotenoids protect plants against over-illumination. The ultrafast dynamics of carotenoid excited states in spinach leaves were investigated upon intensity-dependent, selective carotenoid excitation through femtosecond pump-probe spectroscopy.
