Scheme 2.

Scheme 2

The base-to-base hole transfer of Reaction 12 in Scheme 1 is shown here, specifically, for a hole on cytosine, Cyt•+. The hole can transfer to an adjacent Gua at a rate kCG(adj) or an opposite Gua at rate kCG(op). But these base-to-base transfer reactions must compete with transfer of the hole from cytosine to its own deoxyribose, at rate of kCdRib. Reaction 9 in Scheme 1 is detailed here for a specific case.
