Classification of molecules into point groups
WebStarting from any edge-hexagon, we proceed counterclockwise along the hole boundary to the next edge-hexagon. Let x 1 be the corresponding direction vector. This vector “deletes” an edge that it crosses over, 1 thus making the vertex on the right a defect point. In a similar fashion, the next edge-hexagon is reached by a direction vector x 2 which also counts … Webmolecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance.
