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