Nuclear Magnetic Analysis

Nuclear magnetic analysis refers to nuclear magnetic resonance spectroscopy (English: Nuclear Magnetic Resonance spectroscopy, referred to as NMR spectroscopy or NMRS), also known as nuclear magnetic resonance spectroscopy. It is a spectroscopic technology that applies nuclear magnetic resonance phenomena to determine molecular structure. Research on nuclear magnetic resonance spectroscopy mainly focuses on the spectra of two types of nuclei, hydrogen spectrum and carbon spectrum.
People can obtain a lot of information from NMR spectroscopy. Just like infrared spectroscopy, NMR spectroscopy can also provide the number and type of chemical functional groups in the molecule, but in addition, it can also provide a lot of information that infrared spectroscopy cannot provide. Nuclear magnetic resonance spectroscopy has a profound impact on natural science research. People can use it not only to study reaction mechanisms, but also to study the structure and function of proteins and nucleic acids. NMR samples for study can be liquid or solid. Zhongke Testing provides nuclear magnetic analysis services and has CMA and CNAS qualification certification.

irradiates the sample with electromagnetic waves of a certain frequency, which can cause the atomic nuclei in a specific chemical structure environment to achieve resonance transition. During the irradiation scan, the signal position and intensity when the resonance occurs are recorded, and the nuclear magnetic resonance spectrum is obtained. The position of the resonance signal on the NMR spectrum reflects the local structure of the sample molecule (such as functional groups, molecular conformation, etc.), and the signal intensity is often related to the amount of relevant atomic nuclei present in the sample.
