The photophysics and photochemistry of DNA is of great importance due to the potential
damage of the genetic code by UV light. Quantum mechanical studies have played a key …

DNA charge transport (CT) chemistry has received considerable attention by scientific
researchers over the past 15 years since our first provocative publication on long-range CT …

A procedure for a detailed analysis of excited states in systems of interacting chromophores
is proposed. By considering the one-electron transition density matrix, a wealth of …

Ultraviolet light is strongly absorbed by DNA, producing excited electronic states that
sometimes initiate damaging photochemical reactions. Fully map** the reactive and …

Biochemical reactions are subject to the particular environmental conditions of planet earth,
including solar irradiation. How DNA responds to radiation is relevant to human health …

In order to prevent the damaging effects of sun radiation in the genetic material, its
constituent chromophores, the five natural DNA/RNA nucleobases cytosine, thymine, uracil …

Multichromophoric biosystems represent a broad family with very diverse members, ranging
from light-harvesting pigment–protein complexes to nucleic acids. The former are designed …

Ultraviolet irradiation of DNA produces electronic excited states that predominantly eliminate
the excitation energy by returning to the ground state (photostability) or following minor …

The study addresses interconnected issues related to two major types of cycloadditions
between adjacent thymines in DNA leading to cyclobutane dimers (T<> Ts) and (6-4) …

Excited electronic states created by UV excitation of the diribonucleoside monophosphates
ApA, ApG, ApC, ApU, and CpG were studied by the femtosecond transient-absorption …
