Abstract

Vapor-phase infrared spectra of the 10 hexachlorodibenzo-p-dioxin isomers were recorded at low microgram concentrations. A unique infrared spectrum was observed for each chromatographically separated or spectrally subtracted mixture component. The structures for individual isomers in each isomer pair were assigned by qualitative valence bond evaluations and empirically derived quantitative estimations of ether linkage asymmetric stretching frequencies and by correlations with characteristic aromatic skeletal stretching vibration patterns.
