✦ Synopsis

Based on the influence of the binding energy in gas chromatographic retention, relationships between the retention indices, 1, on squalane and the heats of formation, AHf, of hydrocarbons (alkanes, alkenes, alkynes and alkylbenzenes) are found. Mean information indices of distances, pb for these compounds are used in order to improve the correlation coefficients of I versus AHf equations.
