Fluorescente spectm of 9-cyanoanthracene polycrystallΓ―ne films and glasses of different viscosities and pokuities are reported. The 490 MI emitting species is identified as the 'crans excimer. The blue-shift of 9-CEIA crystal emission upon increasing temperature is explained in tenns of a temperatue
Optical absorption, fluorescence and Raman spectra of 9, IO-dibromoanthracene have been studied as a function of pressure up to 10 GPa. Raman-active lattice phonons show an abrupt change at about 1.5 GPa which indicates a pressure-induced phase transition. Corresponding measurements of the opttcal a
