The pressure dependence of the quadrupole coupling constant e²Qqzz and electric field gradient tensor asymmetry parameter η have been obtained from the analysis of ¹²⁷l nuclear quadrupole resonance spectra at 77 K. It was shown that the phase transition mechanism in the crystal cannot be described a...
