Streszczenie

QNS spectra of TMACA have been measured at various temperatures in both ferro- and paraelectric phases. Subsequent phase transitions, as connected with releasing reorientational degrees of freedom of the (CH3)NH+3 cations, were evidenced in the QNS data. A model of uniaxial 120° jumps of both the cation and its methyl groups (with similar characteristic times) proved satisfactory in data analysis. This model may be oversimplified in the paraelectric phase.
