Two types of models are postulated for deriving linear quantitative retention-structure models in gas chromatography (GC). They were tested by using GC retention indices for a series of 41 alkylbenzenes and 34 physico-chemical (e.g., boiling point) and calculable (topological, steric and electronic)

## Quantitative structure-retention relationships are used to relate the chromatographic retention of analytes to their molecular structure features. With well selected descriptors quick a priori prediction can be accomplished. The descriptors were distinguished in this study in four groups, namel
