Abstract

The structure of benzene films that were vacuum-deposited on cold-metal substrates to be 5—20 μm in thickness was studied with Raman spectroscopy and X-ray diffraction. Films deposited below 30 K were amorphous. They crystallized when the temperature was raised to about 60 K. If the substrate temperature at sample deposition was set above 45 K, films including crystalline particles were obtained. Structural relaxation in the amorphous state did not take place in an appreciable manner before the crystallization. Only an increase in intramolecular Raman-band intensities was observed during the relaxation in the amorphous state. Such behavior of amorphous benzene is compared with that of amorphous states of other simple organic compounds. The above crystallization temperature is discussed in relation to the previously estimated glass-transition temperature of benzene by referring to NMR data.
