Autor: Franco Molina, Jordan Dezalay, Satchin Soorkia, Michel Broquier, Majdi Hochlaf, Gustavo Ariel Pino, Gilles Grégoire

Publikováno v: Physical chemistry chemical physics : PCCP. 24(41)

Oxidation of the nucleobases is of great concern for the stability of DNA strands and is considered as a source of mutagenesis and cancer. However, precise spectroscopy data, in particular in their electronic excited states are scarce if not missing.
