Hello 

If two chromophores are overlapping their emission and excitation wavelengths and the distance between the two species is beyond the foster radius, then which kind of this energy transfer will would be? For instance, for radiative energy transfer, the two species or chromophores should not within the foster radius (approx 10 to12 nm) and wavelength (em n ex) should not be overlapped. on the other side non radiation process, the above conditions should be follow up. please correct me if i m wrong and would be very thankful for sharing your opinion and knowledge.

Thanks and regards
