Perhaps you should try some spelling variations:
"intermolecular interactions" » "molecular interactions", "molecular interactionss", "intermolecular interactionss"
"intermolecular interaction" » "molecular interactions", "intermolecular interactions"
"molecular interaction" » "molecular interactions"
"molecular detection" » "molecular interactions", "molecular regulation"

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