Treatment of `twinning' in isopropylcyclohexane

Abstract: Isopropylcyclohexane, C₉H₁₈, which is a liquid under ambient conditions, tends to form a glass on cooling. Laser-assisted zone refinement of the frozen solid yielded a crystalline solid, although the sample was not single. The crystal was not really a twin in the usual sense of the term, but the consequences of the multiplicity of the sample could be modelled with a combination of domains generated by twofold rotations about the reciprocal lattice [1k0] directions, where k = 9-12.
