Perhaps you should try some spelling variations:
"interintermolecular interactions" » "theintermolecular interactions", "intramolecular interactions", "intramolecular interaction", "intermolecular interactions", "intermolecular interactionss", "interintermolecular interactionss", "interintermolecular detections", "interintermolecular identifications"
"intermolecular interactions" » "molecular interactions", "molecular interactionss", "intermolecular interactionss", "intermolecular detections", "intermolecular identifications"
"intermolecular interaction" » "molecular interactions", "intermolecular interactions", "intermolecular detection", "intermolecular identification"
"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 interaction") OR ("intermolecular interactions"))) OR ("interintermolecular interactions"))) OR ("molecular interaction")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"intermolecular interaction\") OR (\"intermolecular interactions\"))) or (\"interintermolecular interactions\"))) or (\"molecular interaction\"))".
• Removing quotes may allow a broader search: (((((( intermolecular interaction ) OR ( intermolecular interactions ))) or ( interintermolecular interactions ))) or ( molecular interaction )).
• Adding a wildcard symbol may retrieve word variants: (((((("intermolecular interaction") OR ("intermolecular interactions"))) or ("interintermolecular interactions"))) or ("molecular interaction"))*.
