Across the Rows Diffusion involving Intermediate "Stealth"/C-Dimer State. Here a low energy A-type dimer random walks along the top of a row, rotates, and slips between the rows to be a metastable C-type. The dimer then slowly diffuses along the trough, before climbing to an adjacent row where it resumes its diffusion as an A-dimer. Note that through this process the dimer changes rows.
