Chiral and achiral square-cell configurations; the degree of chirality,onfigurations in the plane. Square-cell configurations can be represented by planar graphs. Various families of planar graphs are chiral in two dimensions. A drawing of a tree in the plane, for example, the letter F, is called a plane tree. Chiral plane trees were counted by Harary and Robinson; thi感情脆弱 发表于 2025-3-25 12:12:29

Book 1991 ranging from the basic quantum mechanical properties of simple of a few atoms to molecular optical activity, asymmetric synthesis, systems and the folding pattern of proteins. Chirality, in both the geometrical and the topological sense, has also been the subject of investigations in various branchGLIB 发表于 2025-3-25 23:01:20
