Abstract: The growth of ultrathin films of acetylene on KCl ͑100͒ single-crystal surfaces has been studied by means of low-energy electron diffraction ͑LEED͒ and polarization infrared spectroscopy ͑PIRS͒ in transmission geometry at 40 K. IR spectra in the region of the asymmetric stretch vibration 3 and the asymmetric bending mode 5 were recorded at different coverages. The PIRS spectra as well as the observed ͑ ͱ 2 ϫ ͱ 2͒R45°d iffraction pattern with two glide planes are consistent with a parallel orientation of the m…
