IR spectroscopic studies have been carried out on samples, which were prepared from benzene at at relatively high pressure and low self-bias voltage region. The samples show well-resolved spectral features both in the sp3- and the sp2-hybridized spectral regions. The spectral resolution and separation of bands in the sp2 region, and the good signal-to-noise ratio allows Gaussian decomposition of the distinct bands, even in the more crowded sp3 region. The C-H vibrations show two different neighborhoods, a nearly stress-free, and a highly stressed one. By increasing the deposition voltage, the amplitude of the stress-free region decreases.
