Distributions of energy levels of MOs existing near the HOMO (H) and LUMO (L) for the B-form double-strands having the base sequence 5’-CAG-3’ constructed with LNA (L), PNA (P), RNA (R) and DNA (D) single-strands. The HOMOs for PNA-RNA, LNA-LNA, PNA-DNA and DNA-DNA are doubly degenerate as shown in Table V. These HOMOs are indicated by H*. It is noted that the results for A-form double strand are listed for RNA-RNA, because A-form is more stable than B-form for only RNA-RNA.
