Dichroism in helicoidal crystals
WebJan 1, 2015 · Magneto-chiral dichroism (MχD) is a non-reciprocal, i. e. directional, effect observed in magnetised chiral systems featuring an unbalanced absorption of unpolarised light depending on the direction of the magnetisation. WebThe term “helicoidal dichroism” is used here to describe the optical consequences of anisotropic absorbers precessing around radii of twisted crystalline fibrils or lamellae. d -Mannitol twists in two polymorphic forms, α and δ.
