Question

The amplitude of the NMR signal caused by the absorption of RF energy at the radio frequency does not depend upon the power of the RF energy applied.

(a) True

(b) False

I had been asked this question in semester exam.

My question comes from Sensivity Enhancement for NMR Spectroscopy topic in section Nuclear Magnetic Resonance Spectrometer of Analytical Instrumentation

Answer 1

Right answer is (b) False

The explanation is: The amplitude of the NMR signal caused by the absorption of RF energy at the radio frequency depends on the power of the RF energy applied. It also depends on the sweep rate selected.
