摘要: The direct use of the singlet--triplet energy difference as a new factor selectivity in phosphorimetry is suggested. methodology, which based on synchronous excitation technique, exploits specificity gaps ..delta../sub ST/ between phosphorescence emission band (T/sub 1/ ..-->.. S/sub 0/) and absorption bands (S/sub reverse arrow 0/ or n/ 0/). This approach can greatly improve analysis. Some aspects parameter ..delta.. lambda characterization polynuclear aromatic (PNA) compounds are discussed. differentiation isomeric PNAs illustrated qualitative analysis Synthoil sample given. 5 figures, 2 tables.
