摘要: We measured the 1H, 13 C and 15 N chemical shifts for a series of purine derivatives bearing norbornane substituent in position 9 various substituents 6. The experimental data were complemented with density functional theory (DFT) calculations. comparison calculated provided us information about tautomer conformational equilibria studied compounds.
