RAMAN

Raman spectroscopy is a spectroscopic technique used to observe vibrational, rotational, and other low-frequency modes in a system. Raman spectroscopy is commonly used in chemistry to provide a fingerprint by which molecules can be identified.

    Cavity-enhanced Raman-scattering reveals information on structure and properties of carbon nanotubes. The inherently weak signals are amplified by using special micro cavities as resonator, giving a general boost to Raman spectroscopy as a whole.
