Use of X‐Ray Photoelectron Spectroscopy to Study Bonding in Cr, Mn, Fe, and Co Compounds
TL;DR: In this article, the photoelectron spectra of some 40 transition metal compounds have been measured using AlKα(1487 eV) and MgKα (1254 eV), and the chemical shifts of the core electrons and related these results to a calculated charge based on Pauling's electronegativities.

ESCA studies of Cu, Cu2O and CuO
TL;DR: In this article, the authors studied the behavior of the satellite peaks from copper oxides at 25°C and 400°C, and found that the height of the Cu 2p satellite peaks was lower when the temperature was raised.

Ionization energies in methane and ethane measured by means of ESCA
TL;DR: In this article, the ESCA technique was used to obtain the binding energies for the molecular orbitals in both methane and ethane, and the 2a 1 level was split up in two levels due to the interaction between the carbon atoms.
