View of (a) AT base pair, (b) GC base pair (highlighted are atoms which contribute most to base-base interaction energy) and (c) two neighboring base-pairs (AT and GC). Arrows indicate parts of nitrogen bases whose interaction is taken into account: for bases on the complementary strands only those atoms that face another contribute to the interaction, while for neighboring bases on the same strand all of the atoms contribute.
