Perhaps you should try some spelling variations:
"intermolecular interaction" » "intermolecular detection"
"molecular interaction" » "molecular detection"
"intermolecular interactions" » "intermolecular detections"
"molecular interactions" » "molecular detections"

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