ESCA Studies on Some Bromine Compounds Using an Internal Standard for Calibration

Abstract
The binding energies (Eb) of the Br (3P3/2) level have been recorded for some bromine compounds to characterize the relation between Eb and the atomic charge qBr. As an internal standard the Cls binding energy of the carbons of incorporated phenyl groups have been used. From this relation the charges on the metal atoms in FeBr 4, CoBr2- 4, NiBr2- 4 have been estimated as +1.0, +0.7 and +0.9, respectively.
