We have performed a comprehensive EPR investigation of the quasi-one-dimensional organic systems (TMTTF)2X with centrosymmetrical anions X (X = SbF6, AsF6, and PF6). We observe a strong rotation of g-factor principal axes when the temperature decreases below charge-ordering temperature TCO. The possible origin of this rotation is analyzed on the basis of quantum chemical calculations performed using density functional theory method. A good agreement between theory and experiment is found.Завантаження
