Abstract
We present Raman studies of the vibrational properties of 3,4,9,10-perylene
tetracarboxylic dianhydride (PTCDA) single crystals. Davydov splitting of
internal molecular vibrations due to the interaction of two molecules in a
unit cell was observed. Features of PTCDA crystal lattice vibrations in the
low-frequency region of the Raman spectra are reported. PTCDA films deposi
ted on passivated Si and GaAs surfaces also reveal the specific features of
crystalline structure: Davydov splitting and appearance of phonon lines in
Raman spectra.
