Pressure‐Raman spectra are compared for bulk crystalline 68Zn76Se and ZnSe nanorods. The broadening of TO(Γ) and LO(Γ) is explained by multiphonon mixing and the position of a gap in the 2‐phonon DOS. Nucleation of the phase transition in 68Zn76Se leads to striking similarities in the Raman spectra of retrieved bulk and nanorod samples.
