introduction to spectroscopy, infrared spec, and mass spec

Spectroscopy is an analytical technique used to identify and characterize the components of a given sample by measuring the interaction of the sample with electromagnetic radiation. Infrared (IR) spectroscopy and mass spectrometry (MS) are two of the most popularly used spectroscopic techniques in chemistry, biochemistry, and materials science. IR spectroscopy is used to determine the functional group of a given compound, as well as to identify and quantify the presence of different compounds in a mixture. MS, on the other hand, is used to analyze the masses of ions in a given sample, as well as to determine their elemental composition (Chen, 2019; Zhao et al., 2020). MS and IR spectroscopy are two of the most commonly used analytical tools to characterize the composition and structure of a given sample. In MS, the sample is ionized and the resulting ions are separated according to their mass-to-charge ratio. In IR spectroscopy, the sample is irradiated with infrared radiation, and the resulting absorptions or vibrations in the sample are used to identify and quantify the components of the sample. IR and MS spectroscopy are complementary techniques, with MS providing more detailed information regarding the elemental composition of a sample, while IR provides… Cont…
