Distance Restraints: Intranucleotide

• Sugar-to-sugar. Information about puckering can be extracted basically from d_i(1';2',2''). All other sugar-to-sugar interactions are difficult to determine due to extensive overlapping and also, difficult to be unambiguosly related to sugar conformation.
• Sugar to-base: The most important interactions are d_i(2',2'';6,8) and d_i(1';6,8) although other interactions can also be observed and used to study the sugar conformation and the glycosidic torsion angle.

 

• Base-to-base: d_i(T6;TCH₃)
