Abstract

The K‐absorption edge of copper in different copper systems is studied using a 40 cm Cauchoistype bent crystal spectrograph. It is observed that the K‐edge shifts towards the high‐energy side in all the copper systems under study (except in Cu~2~O). This indicates that the copper ion behaves as a cation (except in Cu~2~O). The shift is correlated with the partial charge on an absorbing ion in the system and the correlation is found to be linear. The partial charge on the copper ion in the systems chalcopyrite, copper perchlorate, and copper fluoborate is determined from the plot of the chemical shift versus the partial charge.
