Question

The purpose of shimming is to:

• A. \( \text{Stabilize the static magnetic field} \)
• B. \( \text{Obtain homogeneity of the static magnetic field} \)
• C. \( \text{Find the lock frequency} \)
• D. \( \text{Obtain homogeneity of the B}_1 \text{ field} \)

Hint:

Proper shimming enhances spectral resolution by optimizing magnetic field uniformity in NMR.

Answer 1

The Correct Option is B

Shimming is performed to ensure homogeneity of the static magnetic field (B\(_0\)), which is crucial for high-resolution NMR spectroscopy. Poor shimming results in broadened spectral lines, affecting signal resolution.
