Which region of electromagnetic spectrum is involved in nuclear magnetic resonance microwave(NMR spectroscopy)?
Correct answer: B. Radio wave
- A. Microwave
- B. Radio wave
- C. Infrared region
- D. X-rays
Explanation
NMR spectroscopy works by applying a radio frequency to the sample, specific to the nuclei of interest. The energy from the radio frequency pulse is enough to flip the nuclei from its Alpha position to the Beta.

About Spectroscopy and Analysis
Spectroscopy studies how substances absorb, emit or interact with electromagnetic radiation. Coverage includes ultraviolet-visible absorption, infrared identification of functional groups, Beer-Lambert law, spectral interpretation and the use of spectroscopic data to identify or determine the concentration of chemical substances.
