Photosynthesis is the natural process that converts solar photons into energy-rich products
that are needed to drive the biochemistry of life. Two ultrafast processes form the basis of …

Chlorophylls and bacteriochlorophylls, together with carotenoids, serve, noncovalently
bound to specific apoproteins, as principal light-harvesting and energy-transforming …

Photosystems I and II convert solar energy into the chemical energy that powers life.
Chlorophyll a photochemistry, using red light (680 to 700 nm), is near universal and is …

The ability to accurately compute low-energy excited states of chlorophylls is critically
important for understanding the vital roles they play in light harvesting, energy transfer, and …

Photosystem II (PSII) is a multisubunit pigment–protein complex that uses light-induced
charge separation to power oxygenic photosynthesis. Its reaction center chromophores …

The GW-Bethe–Salpeter equation (BSE) method is promising for calculating the low-lying
excitonic states of molecular systems. However, so far it has only been applied to rather …

The low quantum yield of photocatalytic hydrogen production in carbon nitride (CN) has
been improved upon via the modulation of both the extrinsic and intrinsic properties of the …

Purple phototrophic bacteria are ancient anoxygenic phototrophs and attractive research
tools because they capture light energy in the near-infrared (NIR) region of the spectrum and …

Photosystem II (PSII) is a membrane‐spanning, multi‐subunit pigment–protein complex
responsible for the oxidation of water and the reduction of plastoquinone in oxygenic …

Bacteriochlorophyll a (Bchl a) and chlorophyll a (Chl a) play important roles as light
absorbers in photosynthetic antennae and participate in the initial charge-separation steps …
