Correlation of structure with retention index for chlorinated dibenzo-p-dioxins

The method presented here allows calculation of the retention indices for the chlorinated dibenzo-p-dioxins under a specific set of experimental conditions, using a limited data set. This technique provides a simple way to obtain retention index data for those isomer standards not readily available. Thus, the technique can aid in structure assignment of specific congeners whether obtained from synthesis or found in environmental monitoring efforts. These calculations have proved highly successful in checking gas chromatographic retention data for internal consistency.
