Ultra low frequency Raman provides important information on a range of sample types, from pharmaceutical polymorphs or carbon nanotubes to heavy metal halides and semiconductors. The low frequency modes can give detail on conformational changes, subtle changes in lattice structure and even gaseous phase bond length – parameters not easily accessible on traditional benchtop equipment.
