Abstract
Glassy films of p-terphenyl were prepared by evaporation onto cold metal substrates. Raman spectra in the lattice and intramolecular vibrational regions were measured to observe the annealing processes of the glassy films for temperatures ranging from 99K to 270K, and compared with those of liquid and polycrystalline samples. It was found that the intramolecular conformational change of the molecule takes place before the long-range ordering in the intermolecular packing.
