About the book
Spectroscopy is a term that is used to describe the interaction of molecules with electromagnetic radiation. As a big science, spectroscopy is used to characterize/detect these molecules based on the produced spectra following their interaction with radiation, both quantitatively and qualitatively. Vibrational spectroscopy is the term used to describe measurements involving both infrared and Raman spectroscopy. As an approach, vibrational spectroscopy is used to measure vibrations resulting from absorption of light/photons. In general, this field has seen major progress specially after grating was first introduced in 1823, and after the first commercial infra-red spectrometer came to the scene. As an established technique that is readily available for researchers and being cost-effective and non-destructive, IR spectroscopy has a realm of applications in different fields. Food analysis, nanoparticles synthesis and characterization, medicine, drug synthesis and analysis, etc. are among the applications. Sampling techniques such as Fourier-transform IR, attenuated total reflection IR (ATR-IR) have served in the development of IR applications in different matrices. With the advances in data sciences and software, coupling of IR spectroscopy to chemometrics serves to combine the advantages of both in terms of time, effort and multicomponent analysis. Yet, being insensitive, and with questionable selectivity, applications of IR are still in a need for future development
