Chapter 15, Problem 15.28E

Interpretation Introduction

Interpretation:

The term symbols of allowed excited states of the ${\text{Co}}^{2+}$ ion with ${}^4{\text{F}}_{9/2}$ electronic ground state are to be stated.

Concept introduction:

A term symbol describes the orbital, spin and total angular momenta of an electronic state. The symbol $L$ represents the vector sum of orbital angular momentum. The symbol $S$ represents the vector sum of spin angular momentum. The symbol $J$ represents the total angular momentum. Therefore, the term symbol is represented as given below.

${}^{2S+1}{L}_J$
