The structures and stabilities of self-assembled guanine quadruplexes, M (9eG) 8+(M= Na,
K, Rb, Cs; 9eG= 9-ethylguanine), have been studied in the gas phase by blackbody infrared …

A dumbbell double-stranded DNA decamer tethered with a hexaethylene glycol linker
moiety (DDSDPEG), with a nick in the centre of one strand, has been synthesised. The …

Binding modes of hydrated Zn2+ and Mg2+ cations to the N7 and O6 positions of guanine
have been characterized by state-of-the-art ab initio model calculations. We show how …

Abstract The binding of Mg 2+, Ca 2+, Zn 2+ and Cu+ metal cations to 2′-deoxyguanosine
has been analyzed, using the hybrid B3LYP, Density Functional Theory (DFT) method and 6 …

Urea undergoes O-protonation in the gas phase to yield a product that is thermodynamically
more stable than the N-protonated isomer, as also is the case in aqueous solution. The …

The structures, relative stabilities, and bonding characteristics of complexes of formamide,
formamidic acid, and (aminohydroxy) carbene with Cu+ have been investigated through the …

An evaluation of the results obtained by the extended kinetic method for a series of
representative bases is presented here. Analysis of the original experimental data is …

Density functional approximation (B3LYP) calculations have been used in order to analyze
the interaction of gold anionic clusters (Au n with n= 2− 4) with uracil ([uracil-Au n]− 1) …

Binding of metal cations to the nucleobases can influence base pairing, base stacking and
nucleobase tautomerism. Gas-phase condensation of dc discharge generated alkali metal …

The gas‐phase acidity of a series of amine–borane complexes has been investigated
through the use of electrospray mass spectrometry (ESI‐MS), with the application of the …
