| Summary: | As many as 15 types of intramolecular hygrogen bonds are determined over 96 conformers of 2´-deoxyguanosine nucleoside by means of the quantum-mechanical analysis (at the DFT B3LYP/6–31G(d, p) theory level) of the electron density topology with Bader's Atoms-in-Molecules theory. The total number of H-bonds is 143, and their types are C2´H2...O5´ (11 H-bonds), C2´H2...N3 (27), C3´H...N3 (20), C5´H1...N3 (4), C5´H1...C8 (1), C5´H2...N3 (13), C8H...O5´ (20), C3´H...HC8 (10), C5´H1...HC8 (3), C5´H2...HC8 (2), O5´H...HC8 (3), O3´H...O5´ (4), O5´H...O3´ (7), O5´H...N3 (9), and N2H...O5´ (9). The conformational, geometric, and electron-topological properties of H-bonds are presented. |
