Abstract

The decomposition of nitromethane on Ni(111) was studied by AES, TPD and IR spectroscopy. Nitromethane decomposed by scission of the NO bonds forming primarily HCN, H₂ and absorbed oxygen. The kinetics were described by first order kinetics with attractive interactions between adsorbed intermediates. The attractive interactions resulted in enhanced infrared absorption of the adsorbed nitromethane molecules. Alignment of molecular dipoles causing an enhanced local field is discussed as a possible explanation of this phenomena. Infrared spectra of CO on Ni(111) are also reported that show the line widths for CO in bridged and on-top sides are different.
