Molecules named by VERIFIED claims about each entry, in the roles the claims give them. Sharing a molecule does not make two smells alike, and an entry with none named may simply have less evidence so far.

What is not known
How similar the two smell to any one person: SmellBook records no measurement of similarity between smells.
Whether the two were ever studied together: their claims come from separate studies unless a source is named for both.
This table compares what SmellBook records about each smell. Rows marked EDITORIAL come from editors' descriptions and links; rows marked VERIFIED come from VERIFIED claims, each resting on a registered source; a claim that could not be checked against the source text says so on its own page. It is not a similarity score: SmellBook shows no percentage or distance between smells.
