Quasiline electron-vibration spectra of acridine and its derivatives

Application of the Shpol'skii effect to quantitative analysis of monomethylphenanthrene isomers

“…Fast frozen solid solutions of phenanthrene in n-alkanes are supersaturated systems far from equilibrium which will manifest complex behavior characterized by inhomogeneity of the solutions and mutual interactions of the solute molecules due either to local changes in the crystal structure of the matrices (33) or to energy transfer in aggregates even at low concentration (22,31,(33)(34)(35)(36).…”
