Interplay between "neutral" and "charge-transfer" excimers rules the excited state decay in adenine-rich polynucleotides (33 views)

Improta R, Barone V

Angew Chem Int Ed (ISSN: 1433-7851, 1521-3773electronic), 2011 Dec 9; 50(50): 12016-12019.

Abstract
The excited states of (dA) 4 oligonucleotides (A=adenine), including the phosphoribose backbone, were studied in water at a fully quantum mechanical level, providing an atomistic description of the main decay paths and a comprehensive interpretation of the experimental data (see picture). After absorption to exciton states delocalized over multiple A bases, the behavior of the excited state is ruled by the interplay of a number of species responsible for different spectral features.
