13. (a) The abbreviated nomenclature for the configurational isomers of 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane (tetramethylcyclam, TMC) are RSRS (+ + + +, trans-I), RRSS (+ - - -), RRSS (+ - - +, trans-III), RSSR (+ + - -, trans-IV) and RRRR (+ - + -, trans-V), where the Cahn-Ingold-Prelog designation refers to the nitrogen configuration in the order 1,4,8,11; the '+/-' indicates whether the amine methyl group is above or below the plane of the macrocycle, again in the order 1,4,8,11; and the 'trans' designation is adopted from Ref. [11b];
