dcterms:description
Since 15N NMR parameters are sensitive indicators of the structural and electronic arrangements in organic compounds2 we used 15N NMR spectroscopy for investigating a set of N7- and N9-substituted purine analogues. The 15N NMR chemical shifts of N7- and N9-purine derivatives were investigated systematically at the natural abundance level of the 15N isotope. The NMR chemical shifts were determined and assigned using GSQMBC, GHMBC, GHMQC, and GHSQC experiments in solution. 15N CP/MAS data were recorded for selected compounds in order to study the principal values of the 15N chemical shifts. Geometric parameters obtained by using RHF/6-31G** and single-crystal X-ray structural analysis were used to calculate the chemical-shielding constants (GIAO and IGLO) which were then used to assign the nitrogen resonances observed in the solid-state NMR spectra and to determine the orientation of the principal components of the shift tensors.
