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

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: (((("intermolecular identification") OR ("molecular interaction"))) OR ("intermolecular interactions")).
• Removing quotes may allow a broader search: (((( intermolecular identification ) or ( molecular interaction ))) or ( intermolecular interactions )).
• Adding a wildcard symbol may retrieve word variants: (((("intermolecular identification") or ("molecular interaction"))) or ("intermolecular interactions"))*.
