Abstract
Photosynthesis is a fundamental process in biosciences and biotechnology that influences profoundly the
research in other disciplines. In this paper, we focus on the characterization of fundamental components, present in
pigment-protein complexes, in terms of their spectroscopic properties such as infrared spectra, nuclear magnetic
resonance, as well as nuclear quadrupole resonance, which are of critical importance for many applications. Such
components include chlorophylls and bacteriochlorophylls. Based on the density functional theory method, we
calculate the main spectroscopic characteristics of these components for the Fenna-Matthews-Olson light-harvesting
complex, analyze them and compare them with available experimental results. Future outlook is discussed in the
context of current and potential applications of the presented results.
