Laser-induced site-selection matrix-isolation fluorescence spectrometry of dibenzacridine isomers.
Laser-induced matrix-isolation site-selection fluorescence spectrometry is used to obtain narrowed-line spectra, linear dynamic ranges and limits of detection for four isomeric dibenzacridines in argon at 15 K. Site-selection fluorescence is used to determine dibenzacridines in two synthetic mixtures, a four-component mixture of the isomeric dibenzacridines and a thirteen-component polycyclic aromatic hydrocarbon mixture. The capabilities of site-selection and Shpol'skii fluorescence spectrometry for the identification and determination of aza-arenes in complex mixtures are compared.
