Chapter 16, Problem 16.1YT

Interpretation Introduction

Interpretation:

In figure $\text{16-3}$, the horizontal lines representing the energies of the $\text{α}$ and $\text{β}$ states and the energy difference between the two states are to be drawn.

Concept introduction:

Nuclear magnetic resonance spectroscopy is a powerful technique to determine the nuclear spin and the splitting of the energy levels in a magnetic field. NMR is used for the testing on the nuclei of atoms. If an external magnetic field is not applied on the nucleus spin states, the $\text{α}$ and $\text{β}$ states remain at the same energy level. The energy level splits in external magnetic field. The higher energy level contains less nuclei than lower energy level. The $\text{α}$ spin is slightly lower than $\text{β}$ state by the difference of $\Delta {\text{E}}_{\text{spin}}$.
