Lorentzian¶

class psi4.driver.p4util.Lorentzian(domain, gamma)[source]¶

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

Parameters:

domain (Union[numpy.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.
