Thermostimulated splitting of Raman active lonsdaleite modes

The results of research of spectroscopic peculiarities of thermostimulated Raman-active lonsdaleite modes, which allow provide correct identification of phases at microscopic dimension of particles are presented. Revealed significant, in comparison with a diamond, thermostimulated changing of spectroscopic characteristics of lonsdaleite with appearance of their partial relaxation in dynamics. Methodological recommendations for proper diagnostics of the lonsdaleite phase are presented.
