    Raman spectroscopy is an analytic technique that is useful for studying the interaction of electromagnetic radiation with matter, more specific, Raman spectroscopy studies general molecular structures and vibrations. Through its characteristic Raman spectra we can obtain chemical and structural information on various substances in a few seconds. This technique is useful to study and measure chemical compounds that have diverse applications such as biomedical, electrochemical, nanoscale electronic and optoelectronics. Another important technique for the analysis of the molecular structures of chemical compounds is Spectrofluorometry. This technique allows us to measure the fluorescence of molecules by measuring the light intensity emitted by a sample after being excited with a specific wavelength. This research used optical spectroscopy, spectrofluorometry, and Raman scattering to characterize and obtain spectra of Silicon (Si), Vanadium Dioxide (VO_2), Zinc Ferrites (ZFO), lignin and Coffee Silver Skin . For the purpose of this research, we used a Raman Spectroscopy model SPEX 1403 of 0.85m Double Spectrometer with a green laser of 533 nm wavelength. In addition, we also used a spectrofluorometer of the Fluoromax-2 series that works under the control of DataMax spectroscopy software. The focus of this research is to elucidate the evolution of optical spectra of chemical and biological compounds. In addition, we seek to electronic structure of materials via observation of different optical spectra. This technique allows us to extract new information for the development and application of new technology.
