Abstract
We present the nature of bonding in chromium chalcogenides (CrX; X = S and Se) using equal-valence-electron-density (EVED) Compton profiles. For the Compton measurements, we have used 20 Ci 137Cs Compton spectrometer. We have also computed the Compton profiles using Hartree Fock (HF) and B3LYP schemes. The experimental EVED profiles suggest more localisation of charge in CrSe in comparison to CrS in the bonding direction. It is concluded that CrSe has more covalent character than that of CrS.
