[NMR] Nuclear Magnetic Resonance Analysis

Nuclear Magnetic Resonance

NMR is a technique used to estimate the structure of compounds by observing the phenomenon (resonance phenomenon) in which atomic nuclei absorb specific electromagnetic waves corresponding to their respective chemical environments when exposed to electromagnetic waves in a magnetic field. The main constituent elements of organic compounds, such as hydrogen and carbon, allow for structural analysis and quantitative analysis of organic compounds through the measurement of 1H and 13C NMR spectra, based on their chemical shifts and integral intensities. Additionally, by analyzing the splitting patterns of the spectra, it is also possible to estimate the spatial relationships between the atomic nuclei. In inorganic compounds, insights regarding their structures can be obtained by measuring nuclei other than 1H and 13C, known as multinuclear nuclei (for example, 19F, 29Si, 31P, etc.). NMR includes solution NMR, used for samples soluble in solvents, and solid-state NMR, used for samples that are insoluble or poorly soluble in solvents.
