This review provides a focused coverage of the photophysical properties of noncanonical
and synthetic nucleobases reported over the past decade. It emphasizes key research …

Epigenetic modifications impart important functionality to nucleic acids during gene
expression but may increase the risk of photoinduced gene mutations. Thus, it is crucial to …

We report ultrafast extreme ultraviolet photoelectron spectroscopy of 6-methyluracil (6mUra)
and 5-fluorouracil (5FUra) in the gas phase and 6mUra and 5-fluorouridine in an aqueous …

5-Formyl-2′-deoxycytidine, an intermediate during the erasure of epigenetic marker 5-
methyl-2′-deoxycytidine, and 5-formyl-2′-deoxyuridine, an oxidative lesion of thymidine …

Using as showcase the DNA dinucleotide 5′-dTpdG-3′, in which the thymine (T) is
located at the 5′ end with respect to the guanine (G), we study the photoinduced electronic …

Nucleosides are sensitive sites towards oxidations caused by endogenous and exogenous
oxidative resources, and a large number of the produced DNA lesions behave as …

Femtosecond fluorescence upconversion experiments were combined with CASPT2 and
time dependent DFT calculations to characterize the excited state dynamics of the …

Time‐dependent density functional theory (TD‐DFT) and multiconfigurational second‐order
perturbation theory (CASPT2) are two of the most widely used methods to investigate …

The high photostability of DNAs and RNAs is inextricably related to the photochemical and
photophysical properties of their building blocks, nucleobases and nucleosides, which can …

The interaction of organic chromophores with light initiates ultrafast processes in the
timescale of femtoseconds. An atomistic understanding of the mechanism driving such …
