Orientation of One-Dimensional Silicon Polymer Films Studied by X-Ray Absorption Spectroscopy
Figure 5
Sketch of the PDMS molecule in which only five silicon atoms are considered: (a) zigzag configuration, (b) helical configuration, (c) definition of the polar angle α in respect to the Si–Si σ vector, and (c) definition of the polar angle γ in respect to the Si–C plane. The structures (a) and (b) are sketched by the WinMOPAC3.9 version of the computer program.
