doppler_broadening

typhon.spectroscopy.doppler_broadening(t, f0, m)[source]

Calculate the doppler broadening half-width half-maximum

\[\gamma_D(T) = \sqrt{ \frac{2\log(2) k_B T}{mc^2} } f_0\]
Parameters:
  • t (float or ndarray) – Temperature [Kelvin]
  • f0 (float or like temperature) – Central frequency [Hertz/invcm]
  • m (float or like temperature) – Mass [kilogram]
Returns
hwhm (like temperature): Half-width half-maximum [Hertz/invcm]
