Interpretation Introduction

Interpretation:

The ${}^{\text{19}}\text{F}$ nuclei in ${\text{SF}}_5^{-}$ have to be classified into chemically or magnetically equivalent groups.

Concept introduction:

Nuclei will be chemically equivalent if they are related by a symmetry operation and have an identical chemical shift.  Nuclei will be magnetically equivalent if they are chemically equivalent and have the same spin-spin interactions with the other nuclei.
