Abstract
Properties of homologous increments of gas chromatographic retention indices have been examined, iRI = RI − 100int(M/14), where M is molecular weight and RI is retention index. Comparing to the characteristics of other organic substances (normal boiling points, permittivity, dipole moments, retention indices and their differences for standard polar and nonpolar phases, indices of boiling points, molecular masses, molar refractions, and their differences), it has been shown that the iRI value can be used as an additional characteristic of polarity.
