From: Non-radiative relaxation of photoexcited chlorophylls: theoretical and experimental study
Excited state energy histogram of the ground state structures of (a) ChlA and (b) ChlB.
The average of 500 conformations shows relative oscillator strengths of the Qy, Qx, B1, B2 and B3 bands and total oscillator strength (solid black), compared to experimental spectra in ethanol (dashed black). Within the simulations, each Chl molecule was initially excited at the B1 band using a Gaussian pulse (red). In the experimental study, both of the Chl molecules were excited at 442 nm.
