<p></p> <p><b>New page</b></p><div>'''TLS (Twin Lattice Symmetry) twinning''' is a term employed to indicate twinning where the [[twin lattice]] does not possess a pseudo-symmetry, differently from what happens in [[TLQS twinning]].<br /> <br /> In TLS twinning, the lattice row / lattice plane [''uvw''] / (''hkl'') defining the cell of the [[twin lattice]] are mutually perpendicular. When this perpendicularity is imposed by the symmetry of the lattice, one speaks of ''intrinsic-TLS'' (''i-TLS''). In all other cases, the conditions of perpendicularity, depend on one or more metric parameters: one then speaks of ''exntrinsic-TLS'' (''e-TLS'').<br /> <br /> <br /> [[Category:Twinning]]</div>
