Singlet-Triplet Energy Difference as a Parameter of Selectivity in Synchronous Phosphorimetry

Published

Journal Article

The direct use of the singlet-triplet energy difference as a new factor of selectivity in phosphorimetry is suggested. The methodology, which is based on the synchronous excitation technique, exploits the specificity of energy gaps ΔST between the phosphorescence emission band (T,→ S0) and the absorption bands (S-1← S0 or Sn-← S0). This approach can greatly improve the selectivity in phosphorescence analysis. Some aspects of the specificity of the parameter Δʎ in the characterization of polynuclear aromatic (PNA) compounds are discussed. The differentiation of isomeric PNAs is illustrated and the qualitative analysis of a Synthoil sample is given. © 1978, American Chemical Society. All rights reserved.
