Hoste, S. published the artcileESCA spectra of pyrazole-copper complexes, Quality Control of 63598-71-0, the publication is Conference on Coordination Chemistry (1987), 103-8, database is CAplus.
The N 1s, C 1s, and Cu 2p ESCA spectra are presented for a series of 7 Cu(II)-pyrazole-NCO complexes. The core level binding energies in these complexes, together with those in the free ligand trimethylpyrazole are discussed in terms of at. charges derived from partial orbital electronegativity and in terms of the relaxation potential model.
