Chapter 14, Problem 14.29E

Interpretation Introduction

Interpretation:

The bond distance of iodine monochloride is to be calculated.

Concept introduction:

The rotational spectrum consists of line equally spaced by the value of $2B$ (where $B$ is the rotational constant). The $B$ consists of information to calculate the bond length of the molecule as it has $I$ (moment of inertia) in its expression $\left(B=\frac{h}{8{\pi }^{2}Ic}\right)$. The moment of inertia is equal to the product of reduced mass of molecule and the square of bond length $\left(I=\mu r^2\right)$.
