1. The @C01249@ of any @S05980-1@ @A00480@ with respect to any other stereogenic centre contained within the same molecular entity. Unlike @A00020@, relative configuration is reflection-invariant. Relative configuration, distinguishing @D01679@, may be denoted by the configurational descriptors $$R^{\text{*}}$$, $$R^{\text{*}}$$ (or l) and $$R^{\text{*}}$$, $$S^{\text{*}}$$ (or u) meaning, respectively, that the two centres have identical or opposite configurations. For molecules with more than two @A00478@ centres the prefix @R05254@- may be used in front of the name of one @E02069@ where R and S have been used. If any centres have known @A00020@ then only $$R^{\text{*}}$$ and $$S^{\text{*}}$$ can be used for the relative configuration.
