The broadest motivation for exploring electron attachment to biological molecules comes
from their important role in radiation damage. Large quantities of secondary electrons with …

Hydrogen bonds play a critical role in nucleobase studies as they encode genes, map
protein structures, provide stability to the base pairs, and are involved in spontaneous and …

Intermolecular static and dynamic fluorescence quenching constants of eight coumarin
derivatives by nucleobase derivatives have been determined in aqueous media. One …

Gold surfaces have been derivatized with 15-base-pair double-stranded DNA
oligonucleotides containing a pendant 5 'hexanethiol linker. The electrochemistry of …

Ab initio molecular orbital calculations of stacked DNA bases were performed at the 3-21G
(*) and 6-31G* levels to elucidate the origin of the 5 '-GG-3 'sequence specificity for the …

Ab initio (MP2/6-31G*(0.25)) interaction energies were calculated for almost 240 geometries
of 10 stacked nucleic acid− base pairs: A⊙⊙⊙ A, C⊙⊙⊙ C, G⊙⊙⊙ G, U⊙⊙⊙ U …

The efficiency of charge migration through stacked Watson− Crick base pairs is analyzed for
coherent hole motion interrupted by localization on guanine (G) bases. Our analysis rests on …

UV radiation creates excited states in DNA that lead to mutagenic photoproducts.
Photoexcitation of single-stranded DNA can transfer an electron between stacked bases, but …

Long-range photoinduced electron transfer has been systematically examined in a series of
small DNA duplexes covalently modified with ethidium and Rh (phi) 2bpy3+ through time …

The anions of the nucleic acid bases, uracil and thymine, were studied by negative ion
photoelectron spectroscopy. Both monomer anions exhibit spectroscopic signatures that are …
