Lecture 12 Summary NMR of liquids and solids

• LIQUIDS
• For two non-equivalent nuclei
• first order (AX spectrum)
• with second order effects (AB spectrum)
• SOLIDS
• For two equivalent nuclei

• Each nuclear spin generates a magnetic field

• Nuclear spin j experiences the magnetic field
  generated by k and vice versa.

• Magnitude of field depends on qjk, rjk and
  direction of spin state.
• Actual field experienced by mj is BzBdipolark
