Perhaps you should try some spelling variations:
"intermolecular identifications" » "intermolecular interactions", "molecular identification", "interlocutor identification"
"molecular interaction" » "molecular interactions", "molecular detection", "intermolecular interactions"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("molecular interaction") OR ("intermolecular identifications")).
• Removing quotes may allow a broader search: (( molecular interaction ) or ( intermolecular identifications )).
• Adding a wildcard symbol may retrieve word variants: (("molecular interaction") or ("intermolecular identifications"))*.
