Abstract
We have measured the temperature dependence of the infrared line shapes of three fundamental vibrations of the ethylidyne species, ≡C–CH3, on the Pt(111) surface. Each of the three line shapes possesses distinctly different properties. The C–C stretch shows the strongest temperature dependence. The full width at half-maximum (FWHM) varies quadratically with temperature from 6 cm−1 at 82 K to 10 cm−1 at 350 K. The frequency of the C–C stretch shows a linear shift from 1125 cm−1 at 82 K to 1117 cm−1 at 350 K. The symmetric C–H stretch shows a temperature independent frequency of 2883 cm−1 and only a small change in full width from 4.1 cm−1 at 82 K to 5.1 cm−1 at 300 K. The symmetric CH3 bend has an unusually narrow full width of 1.2 cm−1 at 82 K which increases to 2.4 cm−1 at 350 K while its frequency remains constant within the experimental error. The results are discussed in terms of current theories of vibrational line broadening for molecules adsorbed on metal surfaces.
