Amorphous biphenyl films were prepared by vacuum evaporation onto cold metal substrates. Structural relaxations (SR) in the films were studied by in situ Raman measurements during annealing. Biphenyl molecules are twisted in the initial amorphous state as in the molten state. A gradual SR which caus
Raman spectra of glucose and fructose are reported in the region 20-4000 cm -1 . The spectra were recorded for the crystalline sugars, amorphous sugars with varying water contents and aqueous solutions with varying sugar contents. The Raman spectra of amorphous carbohydrates have not been reported p
We report the first observation or the resonanoeenhanced triplet&ate Raman scattering in a molecular crystal. Specifically, the resonnnce+nhanccd Raman ratterins from the T1 s&te of naphthalene in the environment of the n~phthalene:2(1,4~~od~te~~uoroben~ne~ crystalline complex is observed by excitin
Resonance fluorescence spectra, obtained by irradiation into vibronic levels of the-first excited singlet state of naphthslene are discussed. These spectra sra compared with the nequilibrated fluorescence" and with a spectrura obtained by irradiation into the second singlet state. Conditions are giv
