    • In the approach of Hughes et al.29 the dipole strength for Chl a was estimated by integration from the absorption band area to be 19 D2, and the excitonic coupling was screened by a factor 1/ε with ε= 3 such that the effective dipole strength in the coupling calculations is just 2.5 D, much less than the 4.0 D used in the present calculations. However, by coincidence the difference turns out to compensate for the shortcoming of the point-dipole approximation, and therefore the same center-to-center distance was obtained as in the present model
