WebMar 1, 2024 · 3. Atom numbers on top of the atoms. Both the previous methods have two issues: First, it can become overly crowded at times when adding the atom numbers and second, the visual appeal goes away. A better way to annotate the atoms is by showing the numbers separate from the atomic symbols. To achieve this, set the atomNote property … WebRing counts can be used as descriptors and as ways to classify structures. One way to compute the ring count is to compute the Euler characteristic: #Rings = #Bonds - #Atoms + #Components. Many chemistry toolkits, though not all, implement a ring finding algorithm which identifies the most chemically relevant rings.
