Structure assignment by retention index in gas-liquid radiochromatography of substituted cyclohexenes.
Substituents and functional groups cause increase in retention indexes of six-membered ring compounds on apolar and polar columns. These retention index increments (delta I) are characteristic and structure-dependent showing a structure-retention index relationship. The delta I values obtained for methyl and halogen atom substitution, cyclohexenes, and cyclohexanes are useful for predictive purpose in tritium labeling studies for tentative structure assignment of radioactive intermediates not amenable to analysis by conventional techniques.
