Microscopic structure of two domain states and two parallel mutually reversed domain walls in the [\alpha] phase of quartz. The left-hand vertical dotted line represents the domain wall [{\sf W}_{12}], the right-hand line is the reversed domain wall [{\sf W}_{12}]. To the left of the left-hand line and to the right of the right-hand line are domains with domain state [{\bf S}_1], the domain between the lines has domain state [{\bf S}_2].
