Here we employ a fiber-based, high-finesse optical microcavity to detect the Brownian motion of a freely suspended carbon nanotube at room temperature under vacuum. The optical detection resolves deflections of the oscillating tube down to 70 pm=Hz1=2. A full vibrational spectrum of the carbon nanotube is obtained and confirmed by characterization of the same device in a scanning electron microscope. Our work extends the principles of high-sensitivity optomechanical detection to molecular scale nanomechanical systems.</dcterms:abstract> <dcterms:available rdf:datatype="">2013-05-22T06:54:56Z</dcterms:available> <dc:contributor>Hunger, David</dc:contributor> <dc:creator>Stapfner, Sebastian</dc:creator> <dc:rights>deposit-license</dc:rights> <dc:creator>Reichel, Jakob</dc:creator> <dc:date rdf:datatype="">2013-05-22T06:54:56Z</dc:date> <dc:language>eng</dc:language> <dc:creator>Favero, Ivan</dc:creator> <dc:creator>Weig, Eva M.</dc:creator> </rdf:Description> </rdf:RDF>
