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

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