| Abstract: | The traditional approach to calculations of gas-chromatographic retention indices from physicochemical constants of organic
compounds in homologous series does not encompass all possible objects. Forming different taxonomic groups of compounds by
variations in the formal unsaturation, the number of atoms of different elements within molecules, or any complex fragments
of structure/composition makes it possible to calculate unknown retention indices by several independent methods from different
arrays of initial data. The application of simple three-parameter equations provides an accuracy comparable to the modern
interlaboratory error of determination of retention indices for any compounds.
