ABSTRACT
Spectroscopic techniques employ light to interact with matter and thus probe certain features of a sample to learn about its consistency or structure. Consequently, the spectroscopic study of biological cells and tissue is an active area of research, with its primary goal being to elucidate how accurately infrared spectroscopy can determine whether cells or tissues are damaged. Ultraviolet Spectroscopy is useful in the structure elucidation of organic molecules, the presence or absence of unsaturation, and the presence of hetero atoms. Infrared Spectroscopy (IR)spectroscopy has been widely applied in both qualitative and quantitative analysis of herbal drugs. In addition, the application of IR spectroscopy to the detection of illegal additives and the assessment of the quality of herbal medicines by fast inspection has also been proven. Fourier transforms infrared spectrometers, with their high signal-to-noise ratio and high precision in absorbance and wave number measurements, have caused a resurgence of interest in the use of infrared spectra for the identification of biomolecules.
