The condensation and restoration of the soft modes have been found. The soft modes are associated with the structural phase transition from the R32 phase to the P3121 phase. The behavior of the hard modes confirms the structural phase transition close to the tricritical point. The temperature of the structural phase transition T1 = 33 K is established.
