biomedical spectroscopy biomedical spectroscopy biomedical spectroscopy is a multidisciplinary research field involving spectroscopic tools for applications in the field of biomedical science. vibrational spectroscopy such as raman or infrared spectroscopy is used to determine the chemical composition of a material based on detection of vibrational modes of constituent molecules. some spectroscopic methods are routinely used in clinical settings for diagnosis of disease; an example is magnetic resonance imaging (mri). fourier transform infrared (ftir) spectroscopic imaging is a form of chemical imaging for which the contrast is provided by composition of the material.
