Lorentzian

class psi4.driver.p4util.Lorentzian(domain, gamma)

Bases: Lineshape

Lorentzian function on domain, centered at x_0 with broadening gamma.

Parameters:

• domain (Union[ndarray, List[float]]) – The domain of the Lorentzian profile.

• gamma (Callable[[float], float]) – Broadening parameter. This is the full width at half maximum (FWHM).

Notes

Use this profile to model homogeneous broadening.

Methods Summary

lineshape(x_0)	Lorentzian function on Lineshape.domain, centered at x_0 with broadening Lineshape.gamma.
maximum(x_0)	Maximum value of Lorentzian profile centered at x_0.
