Abstract
Absorption and fluorescence spectra and the relative quantum yield of fluorescence of solutions of eosin-blue in various solvents have been studied and the data interpreted in terms of the non-radiative processes occurring in the solution, dimer formation and the dipole moment of eosin. The results seem to suggest a lower value for the dipole moment of the eosin molecule in the excited state than in the ground state.
Резюме
Исследовались спектры поглощения и флуоресценции и относительный квантовый выход флуоресценции раствора эозина-синего в различьых растворителях. Данные толкуются с точки зрения неизлучающих прсцессов, проиеходящих в растворе, образования димера и дипольного мсмента эозина. На основе результатов показывается, что молекула эозина в возбужденном состоянии имеет более низкий дипольной момент, чем в основном
