Since January 2015 on the basis of the former Centre "Nanobiophotonics" a new structural subdivision – Sector of Raman spectroscopy – has started its activities in FLNP. Studies are performed within the theme “Multimodal platform for Raman and nonlinear optical microscopy and microspectroscopy for condensed matter studies”.

Along with neutron and synchrotron research, optical spectroscopy and microscopy occupy its own niche in the study of properties, structure and diagnostics of condensed matter. In particular, the Raman spectroscopy is a spectroscopic technique to study vibrational, rotational, and other low-frequency modes in a system at the molecular level in the range of about 10 to 4000 cm-1. It relies on inelastic scattering, or Raman scattering of monochromatic light. Raman spectra are very sensitive to the nature of chemical bonds in organic molecules and polymer materials, as well as in inorganic crystal lattices and clusters. For this reason, each chemical compound has its own individual Raman spectrum, which is a unique fingerprint for a given material.
