39. Another possibility is that this Rh-C contribution arises from some hydrocarbon formed during the decarbonylation process; the point is addressed in the Discussion section.

41. The stated bond distance for this contribution may be spuriously short as a consequence of multiple scattering effects that were not taken into account by the reference file used. Because the assignment of this nonbonding shell, which is located far from the absorber (Rh) atom in comparison with the shells (Rh-Rh and Rh-support) of interest, is tentative and its exact geometry relative to the absorber atom not well-defined, no attempt was made to correct for the influence of multiple scattering.
