Abstract
Multilayer condensed films of trimethyl(methylcyclopentadienyl)-platinum(IV) (MeCpPtMe3) have been exposed to low-energy electrons at incident electron energies of 15, 30, and 500 eV. The reactions occurring under exposure have been investigated using high-resolution electron energy loss (HREEL) spectroscopy. The observed changes in the HREEL spectra upon exposure are similar for the three different energies. Contrary to previous results obtained for electron irradiation at 500 eV using reflection absorption infrared spectroscopy (RATRS) and pointing toward a complete loss of hydrogen a comparable electron exposure in the present experiment yields a product that still contains a significant amount of C-H bonds. In accord with results from thermal desorption spectrometry also obtained after exposure to electrons at lower electron energy, a material is obtained that does not evaporate at room temperature. A crude estimate suggests that the overall reaction rate is consistent with previous results.
