【Abstract】 According to chromatographic thermodynamic theory from the unified form of retention equations the relationship of retention index I of gas chromatography with retention equation coefficients a and c of liquid chromatography has been deduced. It is found that there exists a linear relationship of I with a and c in compounds similar in struture, but effects of hydrogen bond energy and dipole moment should be considered. Thus a method of conversion between gas chromatographic and reversed _ phase chromatographic retention values was suggested. Those formulas were confirmed by experimental data in references on chlorobenzols.更多还原
