The light-harvesting system II (LH2) from Rhodospirillum (Rs.) molischianum is a two-ring circular aggregate composed of eight weakly coupled bacteriochlorophylls-a (BChls-a) in the B800 ring and sixteen strongly coupled BChls-a in the B850 ring. The linear-scaling localized-density-matrix (LDM) met...
