Explain the derivation of the absorption coefficient and index of refraction of a gas of atoms,...

Explain the derivation of the absorption coefficient and index of refraction of a gas of atoms, and discuss what the final results imply that we will see in experiments when we shine light through a gas and how the results relate to the atomic states in the atoms. Please focus on the quantum mechanics explanation and results in your answer.
