    utilising mixture of different bacteriochlorophyll and carotenoids absorbing photons of different wavelengths‚ Rhs acidophila can efficiently utilise the entire spectrum of light. Hence more energy per quanta can be fed into reaction centre where photochemistry takes place. Interestingly the characteristic strong absorption by RG at 400-500nm is a result of transition of electrons from ground state (S0) to second singlet excited state (S2). In RG this transition is very strong corresponding to large
