Almost all of the energy that sustains life on Earth was captured from sunlight during the process of photosynthesis. In the first step of this process, photons are absorbed by aggregates of pigment molecules called ...

A femtosecond transient absorption spectroscopy system was developed and used to characterize the charge-transfer processes which take place between photo-excited porphyrin and C60-fullerene supramolecular donor-accept ...

In plants, the life-sustaining process of photosynthesis begins when molecular light-harvesting complexes capture sunlight. In order to understand the role and function of these complexes, they are often characterised with ...

Coherent control and transient absorption spectroscopy techniques have been used widely in biophysics to manipulate and study ultrafast molecular dynamics such as excitation energy transfer, internal conversion and ...

The fundamental mechanisms involved in photosynthesis provide an opportunity to study physical principles that span over both classical and quantum scales. A better understanding of these mechanisms will benefit the ...
