Question

Atoms of CO2 decay from higher to lower level with a spread of frequency 10kHZ. what will be the line shape if broadening mechanism is found Doppler mechanism.

Answer 1

The line shape will be Gaussian:

$$G(\omega)=\frac{1}{\sqrt\pi\Gamma}\text{exp}\bigg[-\frac{(\omega-\omega)^2}{\Gamma^2}\bigg].$$
