The search of a novel non linear optical material is usually done by intelligent assumption and synthesis feasibility. Vibrational spectroscopy is based on vibrational transitions due to absorption and emission of electromagnetic radiations. Vibrational spectroscopic analysis provides a dynamic view of the molecule. Computational chemistry along with vibrational spectroscopy can provide experimentalists with precise information regarding the properties and behavior of materials. These techniques can help resolve issues that cannot be practically achieved due to instrumentation limits. The analysis of the Infrared (IR) and Raman spectra is now helpful not only for the structural characterization of molecular compounds, but also to derive detailed information on the electronic response from spectroscopic observables.
