Perhaps you should try some spelling variations:
"interintermolecular interactions" » "theintermolecular interactions", "intermolecular interaction", "intramolecular interactions", "intermolecular interactions"
"intermolecular interactions" » "molecular interactions"
"intermolecular detection" » "intermolecular electron", "intermolecular interaction", "intermolecular reactions"

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