The fields of theoretical and computational chemistry have come a long way since their
inception in the mid-20th century. Fifty years ago, only rudimentary approximations for very …

Electron spins permeate every aspect of science and influence numerous chemical
processes: they underpin transition metal chemistry and biochemistry, mediate …

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 …

Photoexcited triplet states play a crucial role in photochemical mechanisms: long known to
be of paramount importance in the study of photosynthetic reaction centres, they have more …

The nature of the photoexcited triplet state of free-base 5, 10, 15, 20-tetrakis (4-
sulfonatophenyl) porphyrin (H 2 TPPS 4−) has been investigated by advanced Electron …

We present a new technique, light-induced triplet–triplet electron resonance spectroscopy
(LITTER), which measures the dipolar interaction between two photoexcited triplet states …

Peridinin-Chlorophyll-a-Proteins (PCPs) are water-soluble light harvesting complexes from
dinoflagellates. They have unique light-harvesting and energy transfer properties which …

Pulsed dipolar spectroscopic methods allow nanometer distance measurements between
pairs of spin labels. We have proposed a new spin labelling approach, based on the …

We explore the potential of orientation-resolved pulsed dipolar spectroscopy (PDS) in light-
induced versions of the experiment. The use of triplets as spin-active moieties for PDS offers …

Triplet-triplet energy transfer from chlorophylls to carotenoids is the mechanism underlying
the photoprotective role played by carotenoids in many light harvesting complexes, during …
