Symmetry organic chemistry
WebIn chemistry, symmetry can be found everywhere, including at the atomic, molecular, and supramolecular level. It is used in molecular spectroscopy, X-ray crystallography, in the … WebSince the discovery of the Frank–Kasper (FK) phase a decade ago, single-component block copolymer systems have offered unique opportunities to explore the structural and phase-transition properties of topologically close-packed FK phases composed of point-particle motifs. Here, we present the formation of complex low-symmetry phases and their …

Sorted by: 2. If there is an infinite number of proper rotations around an axis to match the original of an object with its image -- the example of H C l in the example by @EdV, than this axis is C ∞ and thus (all altogether) C ∞ v like H C N. Otherwise n is an integer number for any rotation 360 ∘ / n for n > 1 ( a reference ).
