X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR) are used to compare the reaction of 1,2-cyclohexanedione (1,2-CHD) with Si(001) and diamond(001) surface dimers under ultra-high-vacuum conditions. 1,2-CHD is k

Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) are used to compare the reaction of acrylonitrile with Si(001) and C(001) (diamond) surfaces. Our results show that reaction with Si(001) and C(001) yield very

The dimers on clean diamond (1 0 0)-2×1 are linked by a σ bond and a highly strained π bond. The weakness of the surface π bond causes the reactivity of this surface to be intermediate between that of an alkene and a bi-radical. We illustrate thi
