Cis binding energy

The XPES of a number of ethylenediamine and cyano complexes, including [Cr(en)3]Cl3 and K3Cr(CN)6, have been measured in order to obtain the difference between die Nls and Cis binding energies. For the en complexes the AE values are related to o donation, and for the cyano complexes are mainly controlled by the nitrogen charge, which depends on the n back-donation. 27... 

X-ray photoelectron spectroscopy (XPS) was performed on an SSI-X-probe (SSX-100/206) spectrometer from Fisons. The energy scale was calibrated by taking the Au binding energy at 84 eV. The Cis binding energy of contamination carbon set at 284.8 eV was used as internal standard value. The analysis of gold and palladium were based on the Au A z, Pd 3ds/2 photopeaks. The intensity ratios I(Au Aisri), I(Pd 3d5/2)/I(Pd 3d3/2X... 

The different electronic environment about Ci and 02(03) in cyclopropyl cation is therefore reflected in the shift in Cis binding energies of. l eV. 

X-ray photoelectron spectroscopy characterization of catalysts was performed on a VG ESCA LABMKII X-ray photoelectron spectrograph under a vacuum of 10 Pa. Mg Ka ray was used as excitation source hv = 1253.6 eV). Cis was used as the internal standard to calibrate the binding energy results.
