We currently have a tag optical-isomerism.
The IUPAC Gold book has the following to offer (DOI: 10.1351/goldbook.O04308):
optical isomers [obsolete]
Obsolescent synonym for stereoisomers with different optical properties. They should be described as diastereoisomers or enantiomers. (Usage strongly discouraged).
I know that the term is still very, very popular in some textbooks; however, I think we should follow the IUPAC recommendation and rename the tag. I don't think there is much need for debate, but there is a question remaining: How do we do it?
Please discuss it with an answer.
