Calculation of gas chromatographic retention indices of organic compounds from the boiling points of their structural analogs

The possibility of calculating gas chromatographic retention indices (I) is discussed. The indices are important parameters for chromatospectral ident ification of organic compounds from the boiling points of their structural analogs (T-b*) using the linear logarithmic equation log I = a log Tb* + bA + c, where A are the structural parameters reflecting the one-re-one posit ion of the compounds being compared ill the corresponding taxonomic groups, including homologous series.
