The process of photosynthesis is initiated by the capture of sunlight by a network of light-
absorbing molecules (chromophores), which are also responsible for the subsequent …

The design of optimal light-harvesting (supra) molecular systems and materials is one of the
most challenging frontiers of science. Theoretical methods and computational models play a …

Excitons are considered as the basic concept used by describing the spectral properties of
photosynthetic pigment-protein complexes and excitation dynamics in photosynthetic light …

Carotenoids are, along with chlorophylls, the most abundant pigments found in nature. They
are present in most organisms including humans but can be synthesized only by plants and …

A practical method for accurate evaluation of the Coulombic contribution to the electronic
coupling for energy transfer at any donor− acceptor separation is reported. The method …

Great progress in the study of structure and dynamics of photosynthetic light-harvesting
pigment− protein complexes has recently resulted in detailed understanding of the light …

Carotenoids are naturally occurring pigments that absorb light in the spectral region in which
the sun irradiates maximally. These molecules transfer this energy to chlorophylls, initiating …

Predicting the electronic structure of extended organic molecules constitutes an important
fundamental task of modern chemistry. Studies of electronic excitations, charge-transfer …

Coherent light sources have been widely used in control schemes that exploit quantum
interference effects to direct the outcome of photochemical processes. The adaptive shaping …

2 1 Introduction the most salient points are just that a molecule can exist in a variety of states
depending on how its electrons are distributed among a set of molecular orbitals, and that …
