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

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 interaction") OR ("interintermolecular interactions"))) OR ((("molecular interaction") OR ("molecular interactions")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"intermolecular interaction\") or (\"interintermolecular interactions\"))) or (((\"molecular interaction\") OR (\"molecular interactions\"))))".
• Removing quotes may allow a broader search: (((( intermolecular interaction ) or ( interintermolecular interactions ))) or ((( molecular interaction ) OR ( molecular interactions )))).
• Adding a wildcard symbol may retrieve word variants: (((("intermolecular interaction") or ("interintermolecular interactions"))) or ((("molecular interaction") OR ("molecular interactions"))))*.
