[0002] Nuclear magnetic resonance is the process in which non-zero spin atomic nuclei absorb electromagnetic waves of a specific frequency and undergo energy level transitions under the action of an external magnetic field. Non-zero spin atomic nuclei have magnetic moments, and their spin energy levels undergo Zeeman splitting under the action of an external magnetic field. Nuclear magnetic resonance spectroscopy is a branch of spectroscopy, and its resonance frequency is in the radio frequency band. The nuclear magnetic resonance detection probe is one of the core components of a nuclear magnetic resonance spectrometer, which is responsible for generating a radio frequency magnetic field to excite the atomic nuclei in the sample and receiving the NMR signals emitted by these atomic nuclei.

Therefore, the present application provides a nuclear magnetic resonance-specific 5-nucleus detection probe to meet the needs. Utility Model Content
