Simulation of physical properties of photosynthetic pigments

Operation co-funded by EU cohesion policy (European Social Fund (ESF)) under the programme EU Structural Funds Investments - LT - ERDF/ESF/CF/YEI (2014LT16MAOP001), managing authority: Finansų ministerija. The source names no beneficiary for this operation. Location: Vilnius County (NUTS LT011); Lithuania. Budget: total eligible expenditure EUR 2,655.26; EU co-financing EUR 2,655.26 (co-financing rate 100%), as stated by the source. Runs 2021-09-01 to 2022-03-31. Source: Kohesio, EU cohesion policy projects managed by national and regional authorities (not CORDIS); selected because its summary names quantum technology. Summary from Kohesio (English machine translation by the source): Photosynthetic systems of different photosynthesis organisms have a very similar structure: it consists of various protein complexes binding light absorbing pigments such as chlorophylls (Chl) or bacteriochlorophylls (Bchl) and carotenoids [1]. Despite this general similarity, depending on the living conditions and the role of the photosynthetic complex in the overall photosynthesis process, the structure and molecular composition of the main light-handed complexes of different organisms differ. For example, the main light-handed complexes LHCII bind Chl a and Chl b pigments, but other strains of chlorophyll — Chl c, d, e and f — are found in various algae and bluishbacterials. On the other hand, as many as 8 different strains of bacteriochlorophylls (Bchl a — Bchl g) can be detected in photosynthetic complexes of various anaerobic bacteria. In order to better understand the peculiarities of the operation of photosynthetic complexes of various organisms, it is necessary to supplement experimental measurements with appropriate theoretical calculations, which, in turn, need to know the characteristics of pigments in light-handling complexes — state energy and electrical dipolar moments, dipolar moments of jump between states, their spatial density, etc. In scientific literature, unfortunately, such structured information provided in one place is not detected. The aim of this project is to fill the gap: using quantum chemistry methods, calculate the physical properties of the pigments involved in photosynthesis of various organisms — different types of chlorophylls and bacteriochlorophylls: the energy of the main and excited states and the static dipolar moments, the dipolar moments of the respective jumps and their spatial density. This would allow new crystallographic data to begin to develop structure-based models in the future and calculate the strong interactions between pigments outside the dot dipoles ARTINIO.
