WebChirality is a difficult phenomenon to wrap your head around, as it is a purely quantum mechanical phenomenon (like spin). It is closely related to helicity, but it is not the same (though it is equivalent for massless particles). Chirality is a fundamental property of a particle; particles which differ in terms of chirality can be viewed as an ... WebApr 28, 2024 · I tried adding Hs using Chem.AddHs(mol) and then try again Chem.FindMolChiralCenters() but didn't get any chiral center. I was wondering if there is a way to recognize this chiral center even if they are not added H and to set the proper chiral tag following some kind of rules.

Do we need separate tags for stereochemistry and chirality?

WebChirality is an asymmetric quality that is relevant in many fields of science. The word chirality comes from the Greek (kheir), which means “hand,” a common chiral item.
