Abstract:

The effects of high pressure on the spectroscopic properties of aromatic hydrocarbons are reviewed. The topics are aromatic molecules in inert matrices, the spectral shift in the absorption, fluorescence and phosphorescence spectra, band broadening, intensities and lifetimes. Specific Interactions between aromatic molecules at high pressures are also included absorption and fluorescence of electron-donor-acceptor complexes, excited state reactions in solution, excimers in polymers, absorption, fluorescence and delayed fluorescence of aromatic crystals. The report summarizes the application of high pressure spectroscopic techniques to one class of organic materials in the last five years. Author
