Abstract
The crystallization of p-nitrophenol molecules (PNP) onto monooriented poly(tetrafluoroethylene) (PTFE) films prepared by friction transfer on glass slides was found to yield highly oriented thin layers of the former species. Polarized Fourier-transform infrared spectroscopy and X-ray diffraction studies clearly show that the thin PNP layers adopt the beta crystal form and have a single-crystal-like orientation with a (001) contact crystal plane, the crystallographic alpha axis being a ligned with the PTFE chain axis. Materials of this outstanding orienta tion are very suitable for analysis by FTIR spectroscopy of the crysta l field effect on molecular vibrations.
