26. The case of benzene adsorbed on the Si(001)-2x1 switching from the di-σ (butterfly) geometry to the tetra-σ one, on a time scale of ca.≈1 h, is well documented [R. A. Wolkow, G. Lopinski, and D. J. Moffatt, Surf. Sci. Lett. 416, L1107 (1998)].
27. The resulting geometry, possessing two Si-C bonds and one Si-N bond, could be thermodynamically more stable than that of the free C≡N, if the penalty induced by bond strains does not overcome the gain in making a new bond (the perturbation due to Si-N bonding should lift the degeneracy of the two π levels of the CN moiety, and give a clear NEXAFS signature).
28. For instance, we have no "topographic" evidence that a CDB unit can only be found on site D at high coverage.
