Question

atoms of CO2 gas decay from upper to lower level with a spread in frequency is about 10kHz. calculate the line shape if the broadening mechanism is found Doppler broadening

Answer 1

The Gaussian line shape will be

$$G=e^{-\text{ln}2\cdot x^2},\\ x=\frac{p-p_0}{w/2},$$

where $p, p_0$ - position on frequency axis, Hz, $w$ - width of the frequency distribution curve where the intensity is half the maximum intensity, Hz.
