Abstract
The non-stationary signal analysis methods based on Joint Time-Frequency Representations appears to be a valuable tool for pulsed PA signal investigation. The thermal deactivation of metastable states (dimers) of Rhodamine 6G in PVA using pulsed photoacoustic spectroscopy was studied. Analysis of Rhodamine 6G photoacoustic pulsed signals involving Wigner-Ville Distribution indicate monomer-dimer forms energy transfer.
