Nitrogen Is Photoelectron Spectra of Octaethylporphyrin (OEP)- and Tetraphenylporphine (TTP)- Complexes of Lanthanides.
Abstract
The nitrogen ls spectra have been investigated for a series of octaethylporphyrin and tetraphenylporphine complexes of lanthanides. The profile of N ls spectrum for each lanthanide porphyrin showed that the four nitrogen atoms were equivalent in the complex. No significant change was detected between the N ls binding energies of the lanthanide porphyrins. A good correlation between N ls line width (FWHM) and a number of unpaired electrons in the complex was found. This result implies the presence of exchange interaction between the ionized N ls core and unpaired valence electrons which are delocalized into N valence shells. The spin density on the N atoms must originate from an overlap/covalent interaction between N and metal valence orbitals. (Author)
