Studying Spatio-Energetic Dynamics in Light Harvesting Complex II using Two-Dimensional Electronic-Vibrational Spectroscopy

Abstract

Abstract:We present two-dimensional electronic-vibrational spectra of the chlorophyll (Chl) binding protein light harvesting complex II (LHCII) from spinach, and of isolated Chl a and Chl b. We show how energy transfer from Chl b to Chl a and subsequent relaxation can be directly observed in LHCII using this multidimensional technique.
