Supplementary information
Fig. S1. The optimized geometries for the bases calculated at the MP2/6-31G** level:
adenine (A), guanine (G), thymine (T), and cytosine (C).
Fig. S2. The optimized configurations for base pairs including m6A (trans and cis
forms) calculated at the MP2/6-31G** level in aqueous solution. H-bonds are
indicated by dotted line, and the corresponding atom numbering is given.
Fig. S3. AIM analysis (MP2/6-31G**, in aqueous solution) of the base pairs with
bond critical points, and the corresponding bond critical points are given.
