On the symmetry properties of the incommensurate phase in thiourea

The symmetry analysis of the incommensurate modulated phase of thiourea reported in [J. Physique 46 (1985) 2187-2195] is revised. Some of its conclusions overstating the relevance of secondary modes for describing the symmetry properties of the modulation are corrected. J. Physique 48 (1987) 2019-2021 NOVEMBRE 1987, Classification Physics Abstracts 64.90 61… CONTINUE READING
