Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What It Helps With?Comprehensive structural elucidation of organic and biological molecules, including conformation and dynamics
2. What is the related topics?Quantum Mechanics, Spectroscopy, Analytical Chemistry, Structural Biology, Materials Science, Medicinal Chemistry
3. How does NMR use magnets and radio waves to learn about molecules?A strong magnetic field makes the tiny nuclear magnets line up, then a radio‑frequency pulse flips them. When they relax, they send a signal that the spectrometer records.
4. Why do atoms need a magnetic field for NMR?The magnetic field orders the nuclear spins so there is a difference in energy between the spins, which lets the radio waves make them resonate.

Nuclear Spin: An intrinsic quantum mechanical property of atomic nuclei that gives them a magnetic dipole moment.
Chemical Shift: The position of a signal in an NMR spectrum, which varies with the electronic environment of the nucleus.
Spin-Spin Coupling: The interaction between the magnetic moments of neighboring nuclei, leading to splitting of spectral signals.
