The formation of 1,3-butadiene and 2,3-dimethyl-1,3-butadiene derived nanostructures on hydrogen-terminated silicon(100)-2×1 was studied using ultra-high vacuum scanning tunneling microscopy and density functional theory modeling. We find that the steric interactions between the methyl groups on 2,3-dimethyl-1,3-butadiene and the surface hydrogen causes 2,3-dimethyl-1,3-butadiene to grow relatively...
Peak assignment is a complex but important task for analyzing the vibration spectra of surface-bound molecules. Here we describe a simple approach for calculating infrared and Raman spectra for surface-bound molecules using a cluster model approach with quantum capping potentials (QCPs). The utility of the approach is demonstrated by comparisons to the measured high resolution electron energy loss...
