Why is the N1-H stretch vibration frequency of guanine shifted upon dimerization to the red and the amino N-H stretch vibration frequency to the blue?
shift of the amino group N-H stretch vibrations in all guanine dimer structuresThree isomers of the guanine dimer (K9K9-1, K9K7-1 and K7K7-1) possessing two N-bonding. Besides the red shifts of the N-H stretch vib...

Benchmark theoretical and experimental study on 15N NMR Shifts of oxidatively damaged guanine
The 15N NMR shifts of 9-ethyl-8-oxoguanine (OG) were calculated and measured in liquid DMSO and in crystal. The calculated change of N9 NMR shift owing to notable N9 can be used for accurate structural interpretation of 15N NMR ...

Guanine adsorption on the Cu(110) surface
The adsorption of guanine on Cu(110) has been studied by soft X-ray that hydrogen bonding causes a significant core level shift in the thin film. At saturation coverage, guanine is tilted at 70 degrees with respect to the s...

G-quadruplex-based structural transitions in 15-mer DNA oligonucleotides varying in lengths of internal oligo(dG) stretches detected by voltammetric techniques
and carbon electrodes. The intensity of guanine oxidation signal at the carbon electrode (peak G(ox)) was observed to increase continuously with number of guanines between 0 and 15, with only a slight positive shift for OD...
