The 13C chemical shifts of nine 2-X-substituted phenetol derivatives were measured together with the 13C chemical shifts of the corresponding X-monosubstituted benzenes. Using an additivity scheme, the ethoxy cisand transortho-SCSs (substituent chemical shifts) at C-6 and C-2, respectively, were det
