Perhaps you should try some spelling variations:
"intermolecular detections" » "intermolecular reactions", "intermolecular interactions", "intermolecular electron"
"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 detections") OR ("molecular interaction")).
• Removing quotes may allow a broader search: (( intermolecular detections ) or ( molecular interaction )).
• Adding a wildcard symbol may retrieve word variants: (("intermolecular detections") or ("molecular interaction"))*.
