Question

The amount of energy available in radio frequency radiation is sufficient for which of the following?

(a) Excite an atom

(b) Vibrate an atom

(c) Vibrate a molecule

(d) Affect the nuclear spin of an atom

I have been asked this question by my college professor while I was bunking the class.

The question is from Principle of Nuclear Magnetic Resonance Spectrometer topic in chapter Nuclear Magnetic Resonance Spectrometer of Analytical Instrumentation

Answer 1

Correct answer is (d) Affect the nuclear spin of an atom

Best explanation: The amount of energy available in radio frequency radiation is sufficient for affecting the nuclear spin of an atom. It constitutes the most fundamental part of spectroscopy.
