Thirty one 2, 6-disubstituted-trans-decalins were chromatographed on carbowax 20M and OV-1 columns, and the retention volumes were converted into the Kovats' retention indices. The increments of some substituents (OH, OCH3, Cl, OAc, CN, COOCH3, C6H5) were determined on the basis of the additivity rule. Elution characteristics of the investigated stereoisomers were reported and discussed.
