Chapter 14, Problem 14.56E

Interpretation Introduction

Interpretation:

The frequency of light absorbed by ${}^{\text{54}}\text{FeH}$ is to be calculated.

Concept introduction:

Infrared spectroscopy (also known as vibrational spectroscopy) is observed due to vibration of the molecule because the energy carried out by IR rays is equivalent to the energy required for the vibration of the molecule. Selection rule for the IR spectroscopy is $\Delta \nu =\pm 1$.
