Abstract

The origin of the non-conservative nature of the circular dichroism spectrum of the CP29 light-harvesting complex in the Qy spectral region is investigated. A structure-based Hamiltonian of coupled Qy transitions, determined previously [Müh et al., Phys. Chem. Chem. Phys., 2014, 16, 11848] is extended by including higher excited states of the chlorophylls and the S0 → S2 transition of carotenoids. Excitonic couplings are calculated with the Poisson-TrESP method, taking into account dipole strengths from experiments on isolated pigments. The coupling between Qy and higher excited states is found to be responsible for the major part of the non-conservativity of the CD spectrum. The remaining part is explained by the intrinsic CD of the chlorophylls that has been estimated from experiments on isolated pigments.

To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
