Fluorescence and absorption spectra of binary mixtures of aromatic hydrocarbons in frozen crystalline solutions

The UV and visible spectra of frozen naphthalene-anthracene, naphthalene-naphthacene, and anthracenenaphthacene solutions have been studied. The effects of component concentrations on the spectra have been determined.In conclusion the authors express thanks to Prof. E. V.Shpol'skii for his constant attention to and interest in the work.
