Peierls distortion path was proved experimentally for dense ZnO nanoparticles prepared by static compression. Electron irradiation caused rock salt (R) to wurtzite (W) transition, following preferential (11-bar1){sub R}//(01-bar11){sub W}; [011]{sub R}//[1-bar21-bar3]{sub W} and then transformation strain induced (111-bar){sub R}//(1-bar011){sub W}; [011]{sub R}//[011-bar1]{sub W}. The two relationships can be rationalized by specified extent of chair- and boat-type Peierls distortions accompanied with band gap opening and intermediate {l_brace}111{r_brace}{sub R} slip for energetically favorable {l_brace}111{r_brace}{sub R}/(01-bar11){sub W} match.
