Summary Correlation equations have been derived which relate the Kováts retention indices ofn-alkylcyclopentenes,n-alkylcyclohexenes andn-alkyl esters of aliphatic acids on the stationary phases OV-101, OV-225 and PEG 20M to column temperature and carbon number in the alkyl chain. The universal equation: $$\begin{gathered} RI = A + B \cdot m + C \cdot \log (m)/m + \hfill \\ D/[(m - 2)^2 + 0.1] + Et \hfill \\ \end{gathered} $$ whereA, B, C, D andE are correlation coefficients,m is the number of carbon atoms in the side chain (forn-alkylcycloalkenes) or in the alcohol chain (for alkyl esters) andt is the column temperature, describes the retention indicesRI of these homologous series with high accuracy (SD〈1 index unit), beginning with the first members of the series.
