Perhaps you should try some spelling variations:
"intermolecular interactions" » "molecular interactions", "intermolecular interactionss", "intermolecular detections", "intermolecular identifications"
"molecular interactionsss" » "molecular interactions", "molecule interactions", "molecules interactions", "molecular interactionssss", "molecular detectionsss", "molecular identificationsss"
"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 interactions") OR ("molecular interaction"))) OR ("molecular interactionsss")).
• Removing quotes may allow a broader search: (((( intermolecular interactions ) or ( molecular interaction ))) or ( molecular interactionsss )).
• Adding a wildcard symbol may retrieve word variants: (((("intermolecular interactions") or ("molecular interaction"))) or ("molecular interactionsss"))*.
