Chapter 14, Problem 14.97E

Interpretation Introduction

Interpretation:

The values of $B_0\text{, }{B}_1$ and $D_J$ for $\text{HCl}$ are to be calculated with the help of the following equations.

$\frac{R\left(J\right)-P\left(J\right)}{4\left(J+\frac{1}{2}\right)}=B_1-2D_J\left(J^2+J+1\right)$

$\frac{R\left(J-1\right)-P\left(J+1\right)}{4\left(J+\frac{1}{2}\right)}=B_0-2D_J\left(J^2+J+1\right)$

Concept introduction:

An electronic state of energy has its own vibrational states. The energy between the electronic states is large followed by vibrational states and then rotational states. During an electronic transition, electron from ground state moves straight to the excited state keeping the internuclear distance constant.
