| Abstract: | The aim of the present paper is to aid biologists understand the complex physical problems of intramolecular energy transfer, in particular, between antenna (bacterio) chlorophyll molecules in vivo.The author has attempted, in the first part of the paper, to explain complicated processes of excitation transfer in a language understandable to readers with knowledge in fundamentals of general physics, but not in molecular optics.The second part of this paper is a critical review relevant to the specifics of physical theories and their applicability to the problem of energy transfer in antenna (bacterio) chlorophylls ((B) Chls) to reaction centers (RCs) in the photosynthetic organisms.Abbreviations PSU
