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