Question

the type of radiation used in NMR spectroscopy is​

Answer 1

Answer:

Like all spectroscopies, NMR uses a component of electromagnetic radiation (radio frequency waves) to promote transitions between nuclear energy levels (Resonance). Most chemists use NMR for structure determination of small molecules.

Answer 2

Answer:

The radiation lies in radiofrequency region of the electromagnetic spectrum used on NMR spectroscopy.

Explanation:

• NMR spectroscopy is a spectroscopic technique even more important than infrared spectroscopy. Many nuclei can be studied in NMR spectroscopy but hydrogen and carbon are most commonly available.
• When hydrogen nuclei (protons) are studied, one can determine the information of number of distinct types of hydrogen nuclei in a molecule as well as the information of regrading the environment of each type.
• The frequency of radiofrequency waves matches with frequency of the electric field generated by precessing nucleus.
• The energy can be transferred from radiations to nucleus, thus causing spin change. This is condition of resonance. We get the signal.
