Abstract

The collective electronic oscillator (CEO) approach was applied to study the electronic excitations of Bchl-a aggregates of LH2 complex of Rs. molischianum. The method is based on computing the optical response of small segments and avoids the quantum chemistry calculations of the whole complex. It provides an effective computational scheme for electronic excitations of large molecules. The electronic couplings are naturally obtained from these computations without invoking the point dipole approximation or similar approximations.
