doppler_broadening

typhon.spectroscopy.doppler_broadening(t, f0, m)

Calculate the doppler broadening half-width half-maximum

$${\gamma }_D(T)=\sqrt{\frac{2\log (2)k_{B}T}{m{c}^2}}{f}_0$$

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]
