[PP1-2-3] Line shape and (natural, pressure, Doppler) broadening

The spectral line is a result of interactions of photon with a quantum system, while it extends over a range of frequencies. The center wavelength of its energy levels may be changed due to Broadening, namely collisions of atoms and molecules or their differences in thermal velocities.
