Discrimination of Diverse Coherences Allows Identification of Electronic Transitions of a Molecular Nanoring

摘要: The role of quantum coherence in photochemical functions molecular systems such as photosynthetic complexes is a broadly debated topic. Coexistence and intermixing electronic vibrational coherences has been proposed to be responsible for the observed long-lived high energy transfer efficiency. However, clear experimental evidence with different origins operating at same time elusive. In this work, multidimensional spectra obtained from six-porphyrin nanoring system are analyzed detail support theoretical modeling. We uncover great diversity separable electronic, vibrational, mixed show their cooperation shaping spectroscopic response. results permit direct assignment vibronic states characterization excitation dynamics. disentanglement molecules extended π-conjugation opens up new avenues exploring coherent phenomena understanding importance function complex systems.
