We focus on (Zn,Be)Se and show by Raman scattering that the original Be-Se doublet at ambient pressure, of the stretching-bending type, turns into a pure-bending singlet at the approach of the high-pressure ZnSe-like rocksalt phase, an unnatural one for the Be-Se bonds. The freezing of the Be-Se stretching mode is discussed within the scope of the percolation model (mesoscopic scale), with ab initio calculations in support (microscopic scale).","authors_text":"Abedalhasan Breidi, Abhay Shukla, Andrei Viktor Postnikov, Chandrabhas Narayana, Fouad El Haj Hassan, Franciszek Firszt, Gopal K.
