Chapter 12, Problem 12A.8BE

Interpretation Introduction

Interpretation:

The factor by which the temperature for ${}^{\text{1}}\text{H}$ nuclei is changed as the relative population increased by $5$ factor has to be stated.  Whether changing the temperature of sample is a practical way of increasing the sensitivity or not has to be predicted.

Concept introduction:

The frequency of electromagnetic radiation is given by resonance condition.  This resonance condition gives an equation that relates the frequency of nuclei with the magnetic field.  The frequency of a nuclei is given by the equation as shown below.

  $v=\frac{{\gamma }_{\text{N}}{B}_o}{2\text{π}}$

The above stated frequency is known as the Larmor precession frequency.  Larmor precession is a phenomenon in which the magnetic moment of nuclei precesses about an external magnetic field.
