Pre-Transition Phenomena During Phase Transition in Potassium Carbonate

  • Published:
Russian Physics Journal Aims and scope

Molecular relaxation processes in potassium carbonate (K2CO3) are investigated using Raman-scattering spectroscopy. It is found that the first-order phase transition is temperature-expanded, and the pre-transition phenomena are observed in crystalline K2CO3. The paper gives theoretical grounds for pre-transition phenomena using the theoretical model of tunneling.
