Perhaps you should try some spelling variations:
"intermolecular interaction" » "intermolecular interactions", "intermolecular detection", "interintermolecular interactions", "intermolecular identification"
"molecular interaction" » "molecular detection", "intermolecular interactions", "molecular identification"
"molecular interactions" » "molecular detections", "intermolecular interactionss", "molecular identifications"
"molecular detections" » "molecular detection", "molecular detectors", "molecule detection"

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