Abstract
The correlation between 13C chemical shifts of DNA and structure parameters (the main axis helix twist angle Ω, base-plane roll angle ρ{variant}, main chain torsion angle δ and propeller twist angle ω) has been discovered and proved indirectly. The carbons relating to the structure parameters have been found and interpreted theoretically. Relative variations in chemical shifts of these carbons obviously reflect purine-purine clash (steric hindrance) and have been compared with sum functions Σ of Calladine-Dickerson rules. It would be possible to provide the information about conformation of DNA from 13C NMR spectra and to observe the structure parameters of Ω, ρ{variant}, δ and ω of DNA in solution.
