In NMR spectroscopy, the spinning nuclei in strong magnetic field must be irradiated by which of the following?
A. Perpendicular and stronger field
B. Perpendicular and weaker field
C. Parallel and stronger field
D. Parallel and weaker field
Answer:B
In NMR spectroscopy, the spinning nuclei in strong magnetic field must be irradiated by which of the following?
A. Perpendicular and stronger field B. Perpendicular and weaker field C. Parallel and stronger field D. Parallel and weaker field
Explanation: In NMR spectroscopy, the spinning nuclei in strong magnetic field must be irradiated by a weaker field which is perpendicular to it. This permits the identification of atomic configurations in molecules.
