Table I.

Bond lengths (Å) and torsion angle (degree) of the ribose sugar part of LNA obtained by the experiments [17] and the present calculations for A- and B-form double-strands. The calculated values are the average over the constructed LNA-LNA, LNA-DNA, LNA-RNA and PNA-LNA. The assignment of each atom is shown in Fig. 1.
