Abstract Laser‐induced mass spectra and UV spectra of dibenzodioxin, dibenzofuran, and two isomers of dichlorodibenzodioxin measured by means of resonance‐enhanced multiphoton ionization in a supersonic molecular beam are presented. The UV spectra show sharp bands and large wavelength shifts both being specific to the number and position of the chlorine atoms. The mass spectra are free of fragments. Therefore the prerequisites for isomer selective ionization and detection of these substances are fulfilled. This encourages further work on polychlorinated dibenzodioxins and dibenzofurans.
