Hardcover Abstract: For more than 1000 luminescent organic substances the most important data are represented as wave numbers of absorption and emission bands, decay times and quantum efficiencies. Additional tables contain further information for restricted groups of substances (figures on typical spectra, wave numbers of sharp single bands, influence of surrounding molecules, etc.).
